Question

short description about atomic radius

Answer 1

Atomic radius is the total distance from an atom's nucleus to the outemost orbital of electron.

Types of radius:

1) Covalent Radius

2) Ionic Radius

3) Matallic Radius

Periodic Trends of Atomic Radius

1) An atoms gets larger as the number of electron shells increase; therefore the radius of atoms increases as you go down the certain group in the periodic table of elements.

2) I general, the size of an atom will decrease as you move from left to the right of a certain period.
