Question

254)_ has the highest ionisation Potentia.
a) Fluorine
b) Chlorine
c) lodine
d) Bromine​

Answer 1

Answer:

fluorine has the highest ionization potential.

Answer 2

Hey—

Fluorine is in period two of the periodic table, meaning that it contains electrons in only the first two energy levels at ground state. It has a higher ionization energy than bromine due to the fact that the valence electrons of fluorine are attracted more strongly to its positively charged atomic nuclei. This is because fluorine atoms have only two energy levels, so there is no significant shielding effect . Therefore it requires a higher ionization energy to remove a valence electron from fluorine.
