Number of protons in the nucleus is the atomic number.
The number of protons is equal to the atomic number of a chemical element.
Two particles are considered. they are protons and nrutrons
The number of protons as well as the number of electrons.
Atomic number is same as the number of protons and number of electrons.
The mass number is the sum of protons and neutrons in the atomic nucleus.
The two subatomic particles added together to determine the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but both contribute to the mass of an atom.
If you use 24He notation then the bottom number in the number of protons and electrons and the top number minus the bottom number is the number of neutrons

No, from 80 years.
Number of protons in the nucleus is the atomic number.
The total number of subatomic particles in the nucleus
No, sodium is not a subatomic particle. Sodium is a chemical element with the symbol Na and atomic number 11. Subatomic particles are particles smaller than an atom, such as protons, neutrons, and electrons.
Electrons. The number of valence or "free" electrons an atom has determines how it can bond with other atoms.
