physical chemistry - Can an atom have more than 8 valence electrons? If not, why is 8 the limit?


According to some chemistry textbooks, the maximum number of valence electrons for an atom is 8, but the reason for this is not explained.


So, can an atom have more than 8 valence electrons?


If this is not possible, why can't an atom have more than 8 valence electrons?
