Question

how do you determine the number of total electrons for an atom

Answer 1

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electronsin a neutral atom is equal to thenumber of protons. The mass numberof the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

The number of protons in one atom of an element determines the atom's identity, and the number of electrons determines its electrical charge. Theatomic number tells you the number of protons in one atom of an element. It also tells you the number of electronsin a neutral atom of that element.

Answer 2

the total number of elections are determine by the atomic number of element.
