What do you notice in the number of valence electrons of metals, nonmetals, And noble gases ?

Sagot :

nonmetals valence electron = 4, 5, 6, 7
noble gases are always 0

Metals have lesser valence electrons than non-metals while all noble gases have 8 valence electrons except for the helium, which has 2 valence electrons...
