Question

explain what is atomic size

Answer 1

Atomic size, which is also known as atomic radius, is defined as the distance between the centre of nucleus and the outermost or valence shell.

Various units are used to measure the atomic size:

1. Angstrom
1 Angstrom = 10^(-10) m

2. Picometre
1 Picometre = 10^(-12) m

Atomic size of some elements:
1. Hydrogen ( H ) - 37 pm

2. Lithium ( Li ) - 152 pm

3. Potassium ( K ) - 231 pm
