Four quantum numbers are used to describe electrons in atoms.
Bohr's Diagrams
The atomic number of an element can be used to determine the number of electrons in an atom. It is equal to the number of protons in the nucleus of an atom, which also corresponds to the number of electrons in a neutral atom.
It an atom has 12 electrons and is neutral, then it must be Mg (magnesium), and magnesium has 2 valence electrons which would be used in bonding.
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.

Valence electrons are those that are in the outermost shell of the atom.
Valence electrons are the electrons that are used in chemical bonding. These are the electrons in the outermost energy level of an atom.

Valence electrons are electrons found in the outer orbital (shell of an atom) They are the electrons used for bonding
The electrons that participate in chemical bonds are located in the "valence shell" or outer energy level of that atom. They are known as the valence electrons, and they are the only part of the atom that participates in a chemical reaction.
