Question

Organize the following list of atoms from lowest to highest Electronegativity:

Beryllium, Barium, Strontium, Magnesium, Calcium

Answer 1

Barium<Strontium<Calcium <Magnesium< Beryllium

Step-by-step explanation:

Electronegativity is defined as the ability of an atom in a bond to attract the shared electrons of the bond towards itself.

Electronegativity is a periodic trend that decreases down the group and increases across the period.

Hence, if i want to arrange Beryllium, Barium, Strontium, Magnesium, Calcium in order of increasing electronegativity, i will have;

Barium<Strontium<Calcium <Magnesium< Beryllium
