Question

PERIODICITY OF ATOMIC RADII​

Answer 1

Hey mate!!!

The atomic radius of atoms generally decreases from left to right across a period. ... Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level. These electrons are gradually pulled closer to the nucleus because of its increased positive charge.

Hope it will help you!!!

Atomic Radius

⟹ Ever wondered why different elements in the periodic table behave differently? Just like you and your best friend are two different entities altogether, various elements have some points of difference between them. Properties like valency, atomic radius, ionization enthalpy etc. are the properties of the individual atoms and are directly related to the electronic configuration. In this chapter, we will know more about the concept of atomic radius.

$\underline\bold\red{Types\:of\:Atomic\:Radii}$

❥ Atomic radii are divided into three types:

• Covalent radius
• Van der Waals radius
• Metallic radius
