Question

Define atomic radius and it’s trends( group and period) in the period table

Answer 1

Answer:

Periodic Trends of Atomic Radius

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements. In general, the size of an atom will decrease as you move from left to the right of a certain period.

Answer 2

Answer:

Atomic radius is the distance from the middle of the nucleus and the last valence shell in an atom...

Atomic radius decreases along a period from left to right.. With increase in nuclear charge.

Atomic radius increases from top to bottom of a group, due to increase in number of shells...
