2. How does the octet rule apply to ionic and covalent bonds?
Select all that apply.
Carbon with 4 valence electrons can satisfy the octet rule by sharing one electron with four different hydrogen atoms, each with 1 valence electron.
Carbon with 4 valence electrons can satisfy the octet rule by sharing one electron with four different hydrogen atoms, each with 1 valence electron.
Chlorine with 7 valence electrons can satisfy the octet rule by sharing one electron with a lithium atom with only 1 valence electron.
Chlorine with 7 valence electrons can satisfy the octet rule by sharing one electron with a lithium atom with only 1 valence electron.
Carbon with 4 valence electrons can satisfy the octet rule by gaining one electron from four different hydrogen atoms, each with 1 valence electron.
