Question

Explain why an element with a large atomic radius won't have a high electronegativity

Answer 1

Explanation:

The larger the radius of an atom, the lesser the electronegativity of the atom. This is because of the screening effect.

• Electronegativity of an element is a property that combines the ability of its atom to lose or gain electron.
• It is mostly expressed as the measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.
• The larger an atom, the lesser the nuclear charge on the outermost electrons.
• This weak shielding of these outer shell electrons results in them easily being lost.
