Differentiate between atom , ion and molecules
Accepted Answer
An atom is the smallest unit of an element that retains the chemical properties of that element. It consists of a nucleus containing protons and neutrons, surrounded by a cloud of electrons.
An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge. A positively charged ion is called a cation, while a negatively charged ion is called an anion.
A molecule is formed when two or more atoms bond together chemically. These bonds can be covalent (sharing of electrons) or ionic (transfer of electrons). Molecules can be composed of the same type of atom (e.g., O2) or different types of atoms (e.g., H2O).
