Question

compounds having both positive as well as negative charges have high melting point . Give reason ​

Answer 1

Answer:

Metallic lattice

Most metals have high melting and boiling points as high temperatures and substantial energy is needed to break the strong electrostatic attractions between positive ions and negative electrons. The delocalised electrons can move and carry charge so metals conduct electricity.

Answer 2

Answer:

yes

Explanation:

Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds. Covalent compounds have bonds where electrons are shared between atoms.
