Question

11. Predict the type of bonding in the following molecules
:
(a) Oxygen
b) Calcium oxide
(c) Water
d) Methane
e)amonium ion​

Answer 1

Answer:

Oxygen- covalent

calcium oxide -ionic bonding

water - hydrogen bonding

methane -covalent

ammonium ion -covalent

Answer 2

Answer:

The atomic number of nitrogen is 7.

Its electronic configuration is [He]2s

2

2p

5

To complete its octet it needs 3 electrons.

As the bonding is between 2 nitrogen atoms each of the atom will share 3 electrons with other to complete their octet.

Sharing of electrons results in covalent bonding.

Hence, they form pure covalent bonds.
