Which of the following is likely to form the greatest number of bonds?

a. hydrogen, atomic number 1

b. sodium, atomic number 11

c. nitrogen, atomic number 7

d. neon, atomic number 10

e. oxygen, atomic number 8

Answer is Nitrogen, atomic number 7

The atomic number of nitrogen is 7. Hence, the number of electrons in the nitrogen atom is 7. In the nitrogen, valance electrons are 3 in number in 2P orbital. Its valency is 3. Therefore, it can make three bonds with other elements which is highest among the given options.
