Explanation:
Moving down the group the bonds formed between these elements and other elements such as chlorine become more ionic . The bonding pair is increasingly attracted away from the group 2 element towards the more electronegative element.

The statement, alkaline earth metals have low values of electronegativity; which decrease down the group , is true.
Explanation:
- Electronegativity is defined as the ability of an atom to attract electrons or a pair of electron towards itself. Smaller is the size of an atom more will be the force of attraction exerted by its nucleus towards another atom in order to attract the electrons.
- Alkaline earth metals are group 2 elements and as they all are metals hence, they tend to lose electrons in order to attain stability. As we move down the group, there occurs an increase in atomic size of the elements.
- Due to this force of attraction between nucleus of the atom and its valence electrons is very less because of shielding of electrons. Hence, atoms become electropositive in nature and not electronegative.
