Answer:
Explanation:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
Answer:

Explanation:
KE = .5mv^2
So when we decrease the velocity by half, we end up losing three fourths of net energy due to that value being squared.
