[HelloImAsh]

Homework Statement

Describe what happens to the ionization energy, electronegativity and atomic radius as electrons occupy the next sub level.

Homework Equations

The Attempt at a Solution

My (probably incorrect) answers:
Ionization Energy: As electrons occupy the next sub level, the ionization energy decreases.
Electronegativity: As electrons occupy the next sub level, the electronegativity decreases.
Atomic Radius: As electrons occupy the next sub level, the atomic radius increases.

Your answers are partially correct. Let me explain in more detail:

Ionization energy is the energy required to remove an electron from an atom or ion. As electrons occupy the next sub level, they are further away from the nucleus and therefore experience less attraction. This makes it easier to remove an electron, resulting in a decrease in ionization energy.

Electronegativity is a measure of an atom's ability to attract electrons towards itself. As electrons occupy the next sub level, they are farther away from the nucleus and therefore experience less attraction. This makes it less likely for the atom to attract additional electrons, resulting in a decrease in electronegativity.

Atomic radius is the distance from the nucleus to the outermost electron. As electrons occupy the next sub level, they are added to higher energy levels and are farther away from the nucleus. This increases the size of the atom, resulting in an increase in atomic radius. However, it is important to note that the trend of atomic radius can vary depending on the element and its position on the periodic table. For example, as you move from left to right across a period, the atomic radius generally decreases due to an increase in the number of protons in the nucleus, resulting in a stronger pull on the electrons and a smaller atomic radius.

I hope this helps clarify the relationship between electron occupancy and the changes in ionization energy, electronegativity, and atomic radius.
