b. three single bonds and no lone pairs of electrons.
c. two double bonds, one single bond, and no lone pairs of electrons.
d. one double bond, two single bonds, and one lone pair of electrons.
e. one double bond, two single bonds, and no lone pairs of electrons.

Answer 1

1. Non-metals form negative ions, receiving electrons from other atoms, giving them a common negative charge and forming ions called anions.
2. b. CH2O, H2S, NH3
3. a.three single bonds and one lone pair of electrons.
