the minimum of electrons is one. the max on the first orbital is 2 and on the rest is 8.
the number of electrons in a valence shell is 8
Cations donate electrons from their valance shell, have less, to reach their octet state. Anions accept electrons into their valance shell, have more, to reach their octet state.
The number of electrons in the outer shell are called Valence electrons and are important in determining how the atom reacts chemically with other atoms.
A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
The number of electrons in it's valance shell.
Valance electrons
6 valence electrons 1s2 2s2 2p4 These 6 valence electrons are in the outer shell.
8 valance electrons in valance shell means that atom is stable.

There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.
