Answer 2

Correct question:

Which of the following has minimum atomic radius?

• Li
• Na
• K
• F

Answer:

★ First let's understand the concept.

Atomic size or atomic radius is the distance between the centre of nucleus to the outermost shell.

• Atomic radius decreases as we go from left to right i.e. across a period
• Atomic size increases as we go down the group

Lithium(Li), Sodium(Na) and Potassium(K) are placed in the same row. Fluorine is a halogen and is placed to the right of the periodic table.

Since, atomic radius decreases as we go from left to right, Fluorine (F) has the minimum atomic radius.

Final Answer:

d. Fluorine (F)
