Answer:
Oxygen atom will strongly attract the shared pair of electrons towards itself.
Step-by-step explanation:
The bond formed between magnesium and oxygen atom is an ionic bond.In this type of chemical bond transfer of electrons takes place from one atom to another.
Electronegativity : tendency to attract shared purr of electrons towards itself.
The transfer of electrons from one atom to another type of an atom depends upon the electronegativities of the atoms.
- Higher the electronegative character in an atom more will be the tendency of that atom to attract the electrons towards itself and form electronegative ion.
- Lower the electronegative character ,more easily it will donate its electrons and form a electropositive ion.
Out of magnesium and oxygen, oxygen is a second most electronegative element in a periodic table which means it will easily attract the shared pairs of electrons towards it self.
