If an atom has three shell and number of valence electrons are two. Is this element metal
cluponka [151]

Answer:

Metal

Element: Calcium

Valency: 2

Explanation:

We already went past 3 shells, just need the 2 electrons after it.

Just skip to the 4th row and count 2 to the right

We end up at Calcium.

Calcium is a metal and we're also on the alkaline earth metals column.

Calcium will need to lose 2 electrons to reach stability, so the valency is 2.
