This apparent contradiction between the chlorine ion and the sodium ion is; due to electrostatic attraction between the nucleus and the electrons.
As we know, there's a periodic trend for atomic radii in the periodic table; the trend is as follows;
- <em>Atomic radius increases down a group and reduces across the period.</em>
Elements get larger down the group and this explains the trend down a group.
- However, atomic radius decreases across a period because the more Valence electrons there are in an element, the more the electrostatic attraction between the positively charged nucleus and the negatively charged electrons.
Consequently, when Chlorine forms an ion by gaining an electron, the electrostatic attraction between its nucleus and electrons increases and the the atomic radius decreases.
On the other hand, when sodium forms an ion by losing an electron, the electrostatic attraction between its nucleus and electrons decreases and the the atomic radius increases.

According to the ACT website you will, "
The value of xy from the given equation is (y ²z²)(√x÷ z²)
<h3>How to solve equation?</h3>
x = y ²z²
make y the subject
y² = x ÷ z²
y = √x÷ z²
xy = x × y
xy = (y ²z²)(√x÷ z²)
Therefore, the value of xy from the given equation is (y ²z²)(√x÷ z²)

Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
