Atomic Radius

Question 1

Atomic radius

Answer 1

Atomic Radius:
The size of an atom. The distance from the nucleus to the valence electrons.
Atomic Radius Decrease moving to the right of the periodic table.
Atomic Radius increases moving down the periodic table.
It decreases moving tram left to right across the table as the effective nuclear
charge increases.. The valence electrans become more strongly attracted to the
nudeus, So the atomic radii decrease across a period.
It increases moving down a group as the number of shells increases, as a
result, atomic radii increases.
