15 The group of elements called the noble gases typically do not chemically react with other
elements. This is true because noble gases tend
to have
A. more protons than other elements.
B. fewer neutrons than other elements.
C. a full outer shell of valence electrons.
D. a single valence electron in the outer shell.

C. a full outer shell of valence electrons.

Explanation:

The noble gases has a full outer shell so they don't have to react with other elements to gain or loose electrons (to have a full outer shell and be stable).

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.

explanation:
