The atomic radii tend to decrease across a period from left to right. The atomic radius usually increases while going down a group.

Due to increase in nuclear charge along a period there is a decrease in atomic radius

Decreases as the force of attraction by nucleus on the valence electrons increases

The atomic radii tend to decrease across a period from left to right. The atomic radius usually increases while going down a group due to the addition of a new energy level (shell). However, diagonally, the number of electrons has a larger effect than the sizeable radius. For example, lithium (145 picometer)...

However, diagonally, the number of electrons has a larger effect than the sizeable radius. For example, lithium (145 picometer) has a smaller atomic radius than magnesium (150 picometer). Atomic radius decreases from left to right across a period, and also increases from top to bottom down a group. read less

Atomic radius decreases in moving from left to right along a period. This is due to an increase in nuclear charge which tends to pull the electrons closer to the nucleus and reduces the size of the atom.

As you move across a period, atomic radius decreases, because, across a period, electrons are added to the same energy level. At the same time, protons are being added to the nucleus. The concentration of more protons in the nucleus creates a "higher effective nuclear charge." In other words, there...
