Question

Match each of the following elements to its configuration for the highest energy electrons

Answer 1

Potassium = 4s¹

Carbon = 2p²

Sulfur = 3p⁴

Barium = 6s²

Xenon = 5p⁶

Step-by-step explanation:

1) Potassium is present in group one.

Its electronic configuration is:

K = [Ar] 4s¹

So its highest energy electrons are 4s¹.

2) Carbon is present in group 14.

Its electronic configuration is:

C = [He] 2s² 2p²

So its highest energy electrons are 2p².

3) Sulfur is present in group 16.

Its electronic configuration is:

S = [Ar] 3s² 3p⁴

So its highest energy electrons are 3p⁴.

4) Barium is present in group 2.

Its electronic configuration is:

Ba = [Xe] 6s²

So its highest energy electrons are 6s² .

5) Xenon is present in group 18.

Its electronic configuration is:

Xe= [Kr] 4d¹⁰ 5s² 5p⁶

So its highest energy electrons are 5p⁶
