What Elements Have The Highest Ionization Energy?
What Elements Have The Highest Ionization Energy?
1 Answer
Askiitians Tutor Team
The elements with the highest ionization energies are typically found in the top right corner of the periodic table, excluding the noble gases. Ionization energy generally increases across a period from left to right and decreases down a group.
Helium (He): As a noble gas, it has the highest ionization energy due to its small atomic radius and stable electron configuration.
Neon (Ne): Another noble gas, neon has a very high ionization energy for similar reasons to helium.
