Predict the number of valence electrons an element in Group 17 will have.

• 1

• 2

• 5

• 7

Why are the noble gases (Group 18) not reactive with other elements?

• Because they are gases.

• Because they are nonmetals.

• Because they are not nice.

• Because they have full energy levels (valence electrons)
