Question

alkaline Earth metals have low values of electronnegativity decreases down the group​

Answer 1

Answer:

Each of these elements has a low electronegativity on the Pauling scale, and the electronegativities clearly decrease down the group. The atoms are decreasingly effective at attracting bonding pairs of electrons. Imagine a bond between a magnesium atom and a chlorine atom.

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
