How many bonds will carbon, nitrogen, oxygen an hydrogen form and why?
Answer: Since they have 4, 5, 6, 1 valence electrons and therefore need 4, 3, 2, 1 to reach their octets, the will form 4,3,2,1 bonds...The 1,2,3,4 rule! Any deviations must mean the atoms carry a charge (due to a loss or gain of electrons)
