Question

Why na+ion has high value of electon gain enthalpy?

Answer 1

If an atom has spontaneous tendency , that is a positive tendency to gain electron then the electron gain process is exothermic & hence its electron gain enthalpy is said to be negative and if the atoms is reluctant to gain an electron i.e. it has a negative tendency to gain an electron and is forced to accept it, the ...
