Question

question 5 of 10 what is the maximum number of valence electrons an element can have? a. 18 b. 10 c. 6 d. 8

Explanation:

Valence electrons are in the outermost shell of an atom. According to the octet - rule, most atoms are stable when they have 8 valence electrons (except for hydrogen and helium which have a duet - rule). Some elements can expand their octet in certain compounds, but the maximum number of valence electrons an element can have in its outermost shell under normal circumstances is 8.

Answer:

D. 8
