All atoms of a particular element have the same number of protons. This is because the number of protons an atom has determines what element it is – the number of protons in an atom’s nucleus determines the element’s identity and is known as its atomic number.
As all atoms of a given element have the same atomic number, they all have the same number of protons. Therefore, any two atoms belonging to the same species (i. e. same element) have the same number of protons.

What always equals the number of protons?
The number of protons in an atom always equals the atomic number of that atom. The atomic number is a measure of the number of protons in the nucleus of an atom. It is usually denoted by the symbol Z and can range from 1 (for hydrogen) to approximately 118 (for ununoctium, the most recently discovered element).
Protons are a subatomic particle found in the nucleus of an atom along with neutrons. Protons have an electrical charge of +1 and a mass of 1. 673 X 10-27 kg. Since protons have the same mass and electrical charge, they are all attracted to the nucleus.
This means that the number of protons in an atom is always equal to the atomic number of that atom.
Are protons of different elements the same?
No, protons of different elements are not the same. Each element has its own unique number of protons in its nucleus. For example, hydrogen has one proton, while helium has two. This is why atoms of different elements have different chemical properties, because it is the number of protons that determines the element.
Each element is represented by its atomic number, which is the number of protons it has in its nucleus. All elements with the same number of protons have the same atomic number, so they are of the same element.
For example, all atoms of oxygen have 8 protons and the atomic number of oxygen is 8.
What element has equal number of protons but different masses?
Ionium (243i) is a rare, extremely long-lived, radioactive isotope of thorium with an atomic number of 90, meaning it has 90 protons in its nucleus. However, the nucleus of ionium also has 143 neutrons and therefore has a mass number of 243, which is significantly greater than the mass number of 90 for regular thorium.
This difference in mass is due to the heavier neutrons present in the nucleus of ionium. Despite having the same number of protons, the dramatically different mass number of ionium gives it different physical, chemical, and nuclear properties when compared to regular thorium, even though they are both isotopes of the same element.
When any atoms have the same proton numbers they have?
When atoms have the same proton numbers, they have the same atomic number and are thus the same element. This is because protons are the particles in the nucleus that determine the identity of an element; the number of protons defines the element, and each element has a unique number of protons.
Thus, atoms with the same proton numbers are atoms of the same element because they both possess the same number of protons. This means they will have the same atomic number, and their electrons will be organized in the same way.
Additionally, they will possess the same physical and chemical properties, regardless of the number of neutrons they possess.
What is it called when atoms have the same atomic number?
When atoms have the same atomic number, they are called isotopes. Isotopes are atoms of the same element that contain the same number of protons and different numbers of neutrons in their nuclei, resulting in varying atomic mass.
Isotopes are generally identified by their mass number, which is the total number of protons and neutrons in the nucleus of the atom, and their relative abundance. Isotopes are found in nature, created by a phenomenon known as ‘natural isotope fractionation’ which is the result of different atomic weights of each isotope.
For example, the element carbon has two naturally occurring isotopes, Carbon-12 and Carbon-13, with 12 being the most abundant.
What Makes 2 atoms the same?
Two atoms can be the same when they are composed of the same number of protons, neutrons, and electrons. All atoms contain a nucleus, consisting of protons and neutrons, surrounded by electrons in orbit.
The number of protons determine the identity of an atom, and this number is unique for each element. Atoms with the same atomic number (number of protons) are atoms of the same element. Elements with the same atomic number, but different mass numbers (number of protons and neutrons added together) are known as isotopes of that element.
Isotopes of the same element share the same chemical properties but may have different physical properties such as boiling point and melting point.
What do two atoms of the same element have in common?
Atoms of the same element share the same atomic number, which corresponds to the number of protons within the nucleus. This means that two atoms of the same element have the same number of protons, as well as the same number of electrons and neutrons, although the number of neutrons may vary due to the several different isotopes of the element.
As a result, atoms of the same element have the same chemical properties and are therefore indistinguishable from one another.
Which number is equal to the number of protons in the atom quizlet?
The number of protons in an atom is equal to the atomic number of that atom. The atomic number is determined by the number of protons in the nucleus of the atom. This is why isotopes of the same element have the same atomic number but different masses; they have the same number of protons, but different numbers of neutrons.
For example, the atomic number of carbon is 6, which means the number of protons in a carbon atom is 6.
