Answer: An atom is electrically neutral. Ions are charged particle formed from atom. Addition of electrons or removal of electrons results in the formation of ions, this means statement A is true.

Now, the building blocks of solids are atoms, and the most of the space of atoms is empty, therefore scientist believes that the most of the part of solids are empty space. Hence, statement B is correct.

Heating water on bunsen burner boils the water over it, doesn't gives any mixture of gases. That's why this statement is incorrect

We can conclude from above explanation that, statement A and B are true.
