Answer:
It decreases
Explanation:
As one moves from lithium to neon across the periodic table, the atomic radius reduces drastically.
- Atomic radius is half of the internuclear distance between two covalently bonded atoms of a non-metallic element.
- It is also half of the distance between two nuclei in the solid state of metals.
- Therefore, across the period it reduces due to increase in the nuclear charge without any attendant increase in the number of electronic shells.
- Consequently, the electrons are pulled more tightly around the nucleus
