Question

what are ionic and molecular compounds? ​

Answer 1

Answer:

Atoms of different elements join together in definite proportions to form molecules of compounds. Compounds can be either ionic compounds or molecular compounds.

Ionic compounds are those compounds that contain charged species of metals and non metals. The charged species are known as ions. An ion is a charged particle and can be negatively or positively charged. A negatively charged ion is called an anion and the positively charged ion is called a cation. Ionic compounds are formed when ionic bonds are formed between different elements through the transfer of electrons. Examples of ionic compounds — sodium chloride, calcium oxide.

Molecular compounds or covalent compounds are those compounds in which the elements share electrons via covalent bonds. Examples — water, ammonia, carbon dioxide.

Answer 2

Answer:

An ionic compound is a chemical compound composed of ions held together by ionic bonding.

Eg: $NaCl,K_{2} O$

Molecular compounds are chemical compounds in which the elements are held together by covalent bonds.

Eg: $N_{2} O,CH_{4}$

Explanation:

Ionic compounds are made up of positively charged ions(cations) and negatively charged ions(anions). But they are overall neutral. They have high melting and boiling points. They are good conductors of electricity when in molten state or in solution.

Molecular compounds are formed by the sharing of electrons. They have generally low melting and boiling points. They have poor electrical conductivity.
