Problem 45P

PROBLEM 45P

Use the Lewis model to explain why each element exists as a diatomic molecule.

(a) hydrogen

(b) iodine

(c) nitrogen

(d) oxygen

Step-by-Step Solution:
Step 1 of 3

Solution 45P

Here, we need to use the Lewis model to explain why each element exists as a diatomic molecule.

The diatomic molecules are molecules composed of only two atoms. Some elements cannot exist by themselves, even when they are isolated from any other type of atom.  Elements of this nature will combine with atoms of the same element in order to be stable.

(a) Hydrogen (H):

The H atom has 1 valence electron. The lewis structure of H atom is

Because H cannot exists by itself and is unstable, it combines with atoms of same element in order to be stable. The lewis structure of H2 molecule is :

                

The 2 valence electrons of each H atom forms a covalent bond and exists as shown below:

                

(b) Iodine (I):

The I atom has 7 valence electron. I exists as diatomic molecule which is made of 2 I atoms. The lewis structure of I atom is

Because I cannot exists by itself and is unstable, it combines with atoms of same element in order to be stable. The lewis structure of I2 molecule is :

                

(c)...
