How many valence electrons does strontium (sr) have

There are 2 valence electrons in Strontium.

Since it is in Group 2 it will have 2 valence electrons. When you draw the Lewis structure for Strontium you'll put two "dots" or valance electrons around the element symbol (Sr).

If this is a true or galse then its true but if not then what is the question?

I'd say your answer would be the sides of a metal pan become hot when the pan is placed on the stove burner
