elements below, indicate how each elements’ valence electrons act in a chemical
reaction. Insert an L if an element loses electrons, a G if the element gains electrons, an E if the
element can either lose or gain electrons, and a U if the element is generally unreactive.

I agree with metals and non-metals. For He and Ne and Ar I would go with a U since they are generally un-reactive.
H can do either. (Loses to form H^+ and gains to form H^-)
Put an L on metals, G on nonmetals, and on He, and Ne, it is neither usually.
tHIS WUESTION SUCKS
H - L (loses 1 electron)
K - L (loses 1 electron)
Li - L (loses 1 electron)
Be - L (loses 2 electrons)
Na - L (loses 1 electron)
Mg - L (loses 2 electrons)
Ca - L (loses 2 electrons)
B - E (can either lose or gain electrons)
C - E (can either lose or gain electrons)
Si - E (can either lose or gain electrons)
N - G (gains 3 electrons)
P - G (gains 3 electrons)
O - G (gains 2 electrons)
S - G (gains 2 electrons)
F - G (gains 1 electron)
Cl - G (gains 1 electron)
He - U (generally unreactive)
Ne - U (generally unreactive)
Ar - U (generally unreactive)
Al - L (loses 3 electrons)
