Question 2
How is the number of unpaired valence electrons in an atom related to the number of bonds that the atom can form?
A) There is no defined relationship between the number of unpaired valence electrons and number of bonds that the atom can form.
B) The number of unpaired valence electrons in an atom is one-half the number of bonds that the atom can form.
C) The number of unpaired valence electrons in an atom is twice the number of bonds that the atom can form.
D) The number of unpaired valence electrons in an atom is the same as the number of bonds that the atom can form.
