Question

show the formation of Na2O and Mgo by Transfer of electrons
​

Answer 1

sodium have atomic number 11 and electronic configuration- 2,8,1 sodium donate 1electron and became electropositive , oxygen gain 2 electron became electronegative .

Magnesium have atomic number 12and electronic configuration-2,8,2Magnesium donate 2electrons and become electropositive, oxygen gain 2 electron became electronegative

Answer 2

Answer:

Thus oxygen accepts two electrons donated by magnesium atom and forms a stable oxide ion O2-. The oppositely changed magnesium ions Mg2+ and oxide ions O2- are held together by a strong force of electrostatic attraction to form Magnesium oxide compound Mg2+O2- or MgO. MgO is an ionic compound.
