The element Ga has how many valence electrons?
1 Answer
Explanation:
For the representative elements (the main group elements), which are groups 1, 2, and 13-18, the number of valence electrons is directly related to what group it's in:
-
Groups 1 and 2 elements have one and two valence electrons, respectively.
-
Groups 13-18 elements have three, four, five, six, seven, and eight valence electrons, in progressive order.
