Question

Explain how potassium has largest atomic radii??​

Answer 1

Answer:

The potassium atom has an extra electron shell compared to the sodium atom, which means its valence electrons are further from the nucleus, giving potassium a larger atomic radius..

2...element potassium

The element potassium (K) present in group 1 has the largest atomic radius.

Answer 2

❥A᭄ɴsᴡᴇʀ࿐:

(D) option

Atomic radius is increases down the Group and decreases across the period.

The radius of calcium is smaller than potassium because both elements lie in the third period of the periodic table. Potassium lies to the left of calcium in the period, and atomic size decreases, going left to right due to increase in the force of attraction by the nucleus.

therefore the correct answer is calcium.
