up and down quarks, 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.

Atomic number of a chemical element = Number of protons = Number of electrons Atomic mass of an isotope (mass number) - Number of protons = Number of neutrons
Number of protons in the nucleus is the atomic number.
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.
Protons plus the neutrons
The mass number is the sum of protons and neutrons in the atomic nucleus.
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

The two subatomic particles are protons and electrons. They match the atomic number on periodic table.
No, from 80 years.
The total number of subatomic particles in the nucleus
Electrons. The number of valence or "free" electrons an atom has determines how it can bond with other atoms.
