Number Of Valence Electrons In Calcium

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n 2) electrons. .For atoms with LESS than 4valence electrons, they’re going to lose/give upelectrons to form positive cations.For atoms with MORE than 4valence electrons, they’re going to gain/stealelectrons to form negative anions.For atoms with 4 valence electrons, it can go either way.For atoms with 8 valence electrons, there is no change.
