Select the correct answer from the choices A, B, C, D which are given. Write down only the letter corresponding to correct answer. With reference to the variation of properties in the Periodic table, which of the following is generally true?
Select the correct answer from the choices A, B, C, D which are given. Write down only the letter corresponding to correct answer. With reference to the variation of properties in the Periodic table, which of the following is generally true?

(a) Atomic size increases from left to right across a period.

(b) Ionization potential increases from left to right across a period.

(c) Electron affinity increases going down a group.

(d) Electro-negativity increases going down a group.

Correct Answer: (b) Ionization potential increases from left to right across a period.

Explanation: With the reference to the variation of properties in the Periodic table, across a period the ionization potential increases from left to right.
