A) Period 2 elements lose electrons.
B) Period 2 elements gain electrons.
C) The nonmetals in period 2 form bonds so that they have a valence shell with eight electrons.
D) The nonmetals in period 2 form bonds so that they have a valence shell with two electrons.
E) Period 2 elements are not alike in any way.

Question

Quizplus · Accepted Answer

The nonmetals in period 2, such as carbon, nitrogen, and oxygen, form covalent bonds to achieve a stable electron configuration with eight electrons in their valence shell, adhering to the octet rule. This is a fundamental principle in chemistry known as achieving a full valence shell for stability.
