Question

Which of these have the highest ionisation energy in the following groups?Why❓
(1,5,17,18)​

Answer 1

Answer:

18

Explanation:

Noble gases have a very stable electron configuration, therefore, they have highest amount of ionization energy within their periods. It decrease down a family because electrons father farther from the nucles are easier to remove...

Answer 2

Answer:

1. 17 group elements have the highest ionization energy.

Explanation:

1. As the 17th group (or) 7A group mainly consists of highly electronegative atoms, the energy required to remove an electron is very high.

2. When compared to other groups having electronegative, these elements have the highest ionization energy because they consist of the highest electronegative atoms like Fluorine (F), Chlorine (Cl), Bromine (Br), and Iodine (I).
