a. li has valence electrons in the n = 1 energy level.
b. si has valence electrons in the n = 3 energy level.
c. ga has valence electrons in the n = 3 energy level.
d. xe has valence electrons in the n = 5 energy level.
e. p has valence electrons in the n = 2 energy level.

b. Si has valence electrons in the n= 3 energy level.

d. Xe has valence electrons in the n=5 energy level

Explanation:

A silicon atom has 14 electrons and 14 protons in its structure. Therefore it has a simple electron configuration of 2.8.4

It therefore has 3 energy levels. The outermost 4 electrons are the valence electrons.

A xenon has an electron configuration of 2.8.18.18.8 = 5 energy levels. The outermost 8 electrons are the valence electrons.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
