Question

Write symbols of cation and anion present in Mgo. Why do ionic compounds have higher melting point

Answer 1

symbols of:
1. cation: Mg²+
2. amion: O²-
Ionic compound have higher melting point because they have ionic bond which has strong force of attraction so they have high melting point.

Answer 2

Answer:

The symbols of 'cation' and 'anion' present in MgO is $\mathrm{Mg}^{2+}$and $\mathrm{O}^{2-}$.  

Explanation:

The cations are the positively charged metallic ions and the anions are the negatively charged non metallic ions. The symbols of 'cation' and 'anion' present in MgO is $\mathrm{Mg}^{2+}$ (cation) and $\mathrm{O}^{2-}$ (anion).

Ionic compounds have a high melting point. This is because, ionic compounds are held together by 'ionic bond' or electrovalent bond. The ionic bonds have a strong 'ionic force of attraction' that holds the 'cations and anions' together strongly. This is why ionic compounds have a high melting point.
