Question

which of the following element have minimum atomic radius. lithium sodium potassium fluorine ​

Answer 1

"The correct answer to the given question is Flourine.

Atomic radius decreases as we move from left to right in a periodic table. So among all the options given in the question, that is, among Lithium, Sodium, Potassium and Flourine, Flourine has the minimum atomic radius as it is a halogen and it is placed at the right of the periodic table as compared to the others given in the question.

"

Answer 2

Fluorine has a minimum atomic radius. The atomic radius of Fluorine is 42 pm.

Explanation:

• Fluorine has a minimum atomic radius.
• The atomic radius of Fluorine is 42 pm.
• As we go from left to right in the periodic table the atomic radius decreases due to increase of number of electrons in the outermost shell of the element.
• The atomic number of Fluorine is 9.
• It has 7 electrons in its outermost shell.
