Question

show the formation of Na2O and MgO by the transfer of electrons. why do ionic compounds have high melting points?​

Answer 1

Answer:

Na2O is therefore an ionic or electrovalent compound. Formation of MgO: It has two electrons in its outermost shell. ... 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. In an ionic compound there is large electrostatic force of attraction between opposite charged ions. To overcome these forces a considerable amount of energy is needed therefore ionic compounds have high melting points.
