Draw a lewis structure for clo4-in which the central cl atom obeys the octet rule, and answer the following questions based on your drawing. the number of unshared pairs (lone pairs) on the central cl atom is: __the central cl atom forms __ single bonds. the central cl atom forms __ double bonds.1b) draw a lewis structure for nh3in which the central n atom obeys the octet rule, and answer the following questions based on your drawing. the number of unshared pairs (lone pairs) on the central n atom is: __the central n atom forms __ single bonds. the central n atom forms __ double bonds.

a. 0, 4, 0

b. 1, 3, 0

Explanation:

a.

In the picture we can see a Lewis structure for ClO₄⁻ in which all the atoms obey the octet rule, that is, they have 8 electrons in the valence shell.

The number of unshared pairs (lone pairs) on the central Cl atom is: 0

The central Cl atom forms 4 single bonds.

The central Cl atom forms 0 double bonds.

For other resonance structures these numbers can change.

b.

In the picture we can see a Lewis structure for NH₃ in which N obeys the octet rule and H atoms complete the valence shell with 2 electrons (duet).

The number of unshared pairs (lone pairs) on the central N atom is: 1

The central N atom forms 3 single bonds.

The central N atom forms 0 double bonds.
