Which of the following statements best describes the behavior of period 2 elements in a covalent molecule?
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 have four valence electrons and form covalent bonds so that they have a valence shell with eight electrons, also known as an octet. This is due to their electronegativity, which allows them to share electrons with other atoms to achieve a stable electron configuration. Therefore, option C is the correct choice.
