Question

define atomic radius, give the periodic trends along a period and in a group Explain with the reasons. Answer na ata ho to plz mt answering kro" ke mujhe nhi ata" plz friends ​

Answer 1

Answer:

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

Essentially, atomic radius decreases across the periods due to an increasing number of protons. Therefore, there is a greater attraction between the protons and electrons because opposite charges attract, and more protons creates a stronger charge. ... Down the groups, atomic radius increases.
