When two or more species have the same number of electrons, they are called isoelectronic species. This term is used to describe atoms, molecules, and ions that have the same number of electrons. Isoelectronic species have the same outermost electron configuration, so they have the same chemical properties and behave similarly.
Examples of isoelectronic species include carbon dioxide and sulfur dioxide, which both have 16 electrons and the same octet electron configuration, as well as helium and neon, which both have 8 electrons and the same duet electron configuration.

What is it called when two or more atoms are combined?
When two or more atoms are combined, it is called a chemical bond. A chemical bond is a strong attraction between two atoms. It is formed when they share or transfer electrons in order to achieve full outer electron shells.
Chemical bonds can be either covalent or ionic, depending on the type and number of electrons being shared or transferred. In covalent bonds, atoms share their outer electrons with each other, and in ionic bonds, electrons of one atom are transferred to another.
Chemical bonds are essential to all aspects of life, as the compounds formed from chemical bonds are the basis of all molecules and thus all matter.
What is two of the same element called?
Two of the same element are referred to as a “diatomic molecule,” which is a molecule made up of two atoms of the same element. There are seven elements in total that can form diatomic molecules – hydrogen (H2), oxygen (O2), nitrogen (N2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2).
Diatomic molecules are incredibly important for life, since all of these elements are essential for the functioning of living organisms, and can often be found in their natural state as diatomic molecules.
What is a group of identical atoms called?
A group of identical atoms is referred to as an element. Elements are the building blocks of all matter, and the ones found in nature exist as atoms. Atoms of an element contain the same number of protons in the nucleus, and they all behave the same when they interact with other atoms.
Elements are typically abbreviated by one or two letters, indicating their atomic number, which is the total number of protons in the nucleus. All the atoms of a particular element also contain the same number of electrons, giving it its chemical properties.
How do you call a group of same species living together?
A group of same species living together is known as a ‘population’. A population consists of all the individuals of a species in a given area. Populations of different species that interact with each other also form a biological ‘community’.
In a community, each species has a unique ecological role and interactions between species can be beneficial, neutral or detrimental. Biological communities are often interconnected in larger networks of interdependent populations known as ‘ecosystems’.
What do you call the group of the same species living together in a same place at the same time?
The group of the same species living together in a same place at the same time is called a population. A population is made up of individuals of the same species, often referred to as members, that live in the same geographical area at the same time.
A population may be large or small and can be made up of a single species of organism or multiple species. A population may also represent a specific niche within an area or ecosystem. Generally, populations are identified and studied by ecologists to gain insights into the behavior, interactions, and impact of different species and the environment they inhabit.
What are the 4 types of symbiotic relationships?
Symbiotic relationships are when two different organisms interact with each other in a way that benefits one or both of them. There are four main types of symbiotic relationships: mutualism, commensalism, parasitism, and protocooperation.
Mutualism is a type of symbiotic relationship in which both organisms benefit from the interaction. An example of mutualism is the relationship between a bee and a flower – the bee collects nectar which it needs to survive, and the flower gets a pollinator in exchange.
Commensalism is a type of symbiotic relationship in which one organism benefits while the other is not directly harmed. An example of this is the relationship between a shark and a remora – the shark is able to swim faster because of the remora, which latches onto its side and is unharmed by the interaction.
Parasitism is a type of symbiotic relationship in which one organism benefits at the expense of the other. An example of this is the relationship between a tick and a dog – the tick feeds on the dog’s blood, but the dog does not benefit from the interaction.
Protocooperation is a type of symbiotic relationship in which both organisms benefit from the interaction, but one organism might have a higher benefit than the other. An example of protocooperation is the relationship between a clownfish and an anemone – the clownfish provides protection for the anemone while the anemone provides a safe place for the clownfish to hide.
What are 2 examples of symbiosis?
Symbiosis is a relationship between two organisms that live in close proximity to one another for an extended period of time. Such a relationship can be beneficial, harmful, or neutral. There are three main types of symbiosis: mutualism, parasitism, and commensalism.
1. Mutualism is a type of symbiotic relationship in which both species benefit from the association. An example is the relationship between clownfish and sea anemones. The sea anemones provide protection for the clownfish from predators, while the clownfish attracts food for the sea anemone to feed on.
2. Parasitism is a type of symbiotic relationship in which one organism, the parasite, benefits while the other organism, the host, is harmed. An example is the relationship between the tapeworm and human.
The tapeworm, a parasite, receives all the benefits of living inside the human, while the human suffers from various symptoms such as anemia, digestion issues, and nutrient deficiencies.
How many electrons does br+ have?
Bromine has an atomic number of 35, which means it has 35 electrons when it’s at its most stable state. When bromine exists as the br+ ion, it losses an electron, and has 34 electrons total.
Which is the larger atom Br or Br -?
The answer depends on how you are interpreting the question. If you are asking which element has a larger atomic number, then Br has an atomic number of 35 and Br- has an atomic number of 34, so Br is the larger atom.
If you are asking which atom has a larger mass, then Br- has a larger atomic mass of 79. 904 compared to the atomic mass of 79. 904 for Br.
Does Br have 8 electrons?
No, Br does not have 8 electrons. Bromine is a chemical element in the halogen group identified with atomic number 35. It has 7 electrons in its outer shell which makes it highly reactive and gives it its distinct color.
As a result, it readily forms compounds with other elements and can exist naturally as diatomic molecules, Br2.
What is the ion of Br?
The ion of Br is Bromide (Br-). Bromine is an element that exists as a diatomic molecule (Br2) in its natural state. It is a member of group 7 of the periodic table and has 7 valence electrons. Because of its 7 valence electrons, it is able to form an anion (or negative ion) called Bromide (Br-).
When Bromine gains an electron, it turns into an anion. Bromide’s charge is -1 and its atomic number is 35. Bromide is an important component in many industrial processes, such as the manufacturing of organic compounds, making explosives, and as a lubricant in motor oils.
Bromide is also found in many foods, including grains, fruits, and vegetables.
Which is the electron configuration for each of the Br -?
The electron configuration for Br- is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5. Br- is primarily composed of the elements, bromine, which has an atomic number of 35, meaning it has 35 protons and electrons. The outermost shell, or valence shell, of the bromine atom consists of five electrons in the 4p orbitals.
When Br- ionizes, an electron is removed from the valence shell and the remaining electron configuration for Br- is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5.
Which atom has the electron configuration 1s22s22p63s23p64s23d7?
The atom with the electron configuration 1s22s22p63s23p64s23d7 is a chromium (Cr) atom. This atom has 24 electrons in total, occupying the shells or orbitals 1s, 2s, 2p, 3s, 3p, and 3d. Specifically, the configuration combines two electrons in the 1s orbital, two electrons in the 2s, six in the 2p, two in the 3s, six in the 3p orbital, and seven in the 3d.
Chromium is an important element due to its excellent corrosion resistance, hard and durable properties, as well as its sustainability. It is found in a variety of alloys, decorative finishes, and industrial processes, and is an essential element in many industries and day-to-day products.
Which is bigger N3 or Al3+?
N3 is bigger than Al3+. This is because Aluminum has an atomic number of 13, which means that it has 13 protons in the nucleus and usually 14 neutrons. This means that its net charge is +3. However, Nitrogen has an atomic number of 7, and therefore it usually has 7 protons and 7 neutrons; its net charge is therefore 0.
Since N3 has a net charge of 0, it is larger than the +3 of Al3+, making it the bigger one of the two.
