Question

What is the atomic radius?

Answer 1

Explanation

• “In a molecule, an atomic radius is defined as half the distance between neighboring atoms of the same element.”
• It is generally stated as being the total distance from an atom's nucleus to the outermost orbital of the electron.
• X-ray or other spectroscopic methods are used to determine an atom's atomic radius.
• There are different types of atomic radii, which are atomic radius, Bohr radius, covalent radius, metallic radius, and Van Der Waals radius.

Variation of atomic radii in Periodic table

• In general, as we move from left to right in a period, the atomic radius reduces, and it increases as we move down a group.
