<span>A. All elements in period 2 are metals: FALSE.

The period 2 include metals and no metals: Li and Be are metals, while B is a metaloid, and C, N, O, and F are non-metals

B. All elements in group 18 are metals: FALSE.

The elements in group 18 are known as noble gases: He, Ne, Ar, Kr, Xe, Rn, and Og (recently named). All of them are non-metals.


C. Metals are found on the left side of the periodic table. TRUE.

With exception of H.

Alkalyne metals are the group 1 (Li, Na, K, Rb, Cs, and Fr).

Alkalyne-earth metals are the group 2: Be, Mg, Ca, Sr, Ba, and Ra.

Those two are the groups most to the left.

The non-metals are all on the right side of the periodic table.

D. Metals are found on the right side of the periodic table. FALSE.

According to the previous information.
