The first(IE_(1)) and second (IE_(2))Ionization energies (KJ/mol) of a few elements designated by roman numerals are given below.Which of these would be an alkali metal?

Text Solution

Verified by Experts

a. `B` is reactive metal since it has minimum to be:
b. `D` is reactive non-metal since it has second minimum `IE_(1)`
c. `A` is noble gas since it has maximum `IE_(1)`
d. `C` forms `MX_(2)`. Since `IE_(2)` of `C` is the least.
