Question

Which of the following are characteristic(s) of molecules. Select all that apply. Molecules consist of two or more atoms. Atoms consist of two or more molecules. All molecules have a positive charge. All molecules have a neutral charge. All molecules have a negative charge.

Answer 1

Answer: The correct statement is molecules consist of two or more atoms.

Explanation:

Molecules is formed by the combination of two more similar or different types of atoms.

Molecules of similar type of atoms are called as molecules of elements. For Example: $H_2,O_2$ etc..

Molecules of different type of atoms are called as molecules of compounds. For Example: $CO_2,H_2O$ etc..

They can have either positive, negative or neutral charge.

Hence, the correct statement of all the given statements is molecules consist of two or more atoms.

Answer 2

Molecules consist of two or more atoms, and all molecules have a neutral charge.

If a molecule has a charge, we call it an ion.

For example, SO₃ is a sulfur trioxide molecule, but SO₃²⁻ is a sulfite ion.
