Question

Alkaline earth metals have low values of electronegativity; which decrease down the group?​

Answer 1

Answer:

because their size goose increase

n tendency to gain electron decrease is known as electronegativity

Answer 2

Answer:

Electronegativity of alkaline earth metals decrease down the group. In a group as atomic number increases, atomic radius increases. Nuclear attraction decreases. The tendency to attract shared pair of electron decreases down the group and hence electronegativity decreases
