Answer :
Answer:
Increases
Explanation:
The atomic radius increases as you go down a periodic table. Across a period which is a row, the atomic radius reduces.
- The atomic radius is taken as the half of the inter-nuclear distance between two covalently boned atoms of non-metallic elements.
- It is also, half of the distance between two nuclei in the solid state.
- Across a period in the periodic table, atomic radii decreases progressively from left to right.
- Down a group it increases from up down.
