The `1^(st), 2^(nd)` and the `3^(rd)` ionization enthalpies. `I_1, I_2, I_3` of four atoms with atomic numbers `n , n + 1, n + 2 and n + 3`, where `n < 10` , are tabulated below. What is the value of n?

Text Solution

Verified by Experts

The correct Answer is:
9
From given data (n + 2) atom is alkali metal which is sodium.
As `n + 2 = 11` so (n = 9)
