Question

Potassium atom is larger than sodium atom. Why?

Answer 1

Potassium atom is in 4th period and sodium is in 3rd period, the number of outermost orbits is greater in potassium than sodium.So the nuclear attractions decreases in potassium which ultimately leads to the larger size of it.

Answer 2

Answer:

K atom contains four electron shells, compared to Na's three (2, 8, and 1) (2, 8, 8,1). So, the potassium atom is larger than the sodium atom.

Explanation:

• All body tissues require the mineral potassium, which is a necessary component. Because it carries a little electrical charge that triggers a variety of cell and neuron activities, it is occasionally referred to as an electrolyte.
• The element sodium is a very delicate silvery-white. To regulate blood pressure and blood volume, the body utilizes salt. In order for your muscles and nerves to function properly, your body also requires sodium.

• In group 1, potassium is positioned below sodium.
• As a result, it has an additional electron shell.
• K atom contains four electron shells, compared to Na's three (2, 8, and 1) (2, 8, 8,1).

Potassium(K) is hence larger than sodium (Na) in size.
