Question

among the elements B, Ne, N, F, Li, Be which has lowest first ionization enthalpy and which has higher ? why?

Answer 1

Explanation:

Li has low I.E . because among all these elements its size is small and have only one electron in its valence shell

Answer 2

Answer:

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.
