Question

Which ionization energy is generally the largest?

Answer 1

Answer:

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.

Answer 2

Answer:

The ionization energy of helium is the highest

Explanation :

• The ionization energy of helium is the highest! Because the electrons in helium are so near to the nucleus, the electrical attraction between them is quite strong. It becomes more difficult to remove one electron as a result of this.

• Across the periodic table, the first ionization energy fluctuates in a predictable fashion. In groups, the ionization energy decreases from top to bottom and increases from left to right over time. As a result, helium has the highest initial ionization energy, whereas francium has the lowest.
