Groups of atoms held together by energy are called a molecule. The energy or force holding the atoms together is called a Chemical Bond,
The Covalent bond involves the sharing of 2 electrons.
Molecule- One or more atoms make up molecules. They may have the same atoms or different atoms if they have more than one. Biological molecules like DNA and proteins can include thousands of atoms.
Chemical Bond- Chemical bonding is the process through which two or more atoms, molecules, or ions establish a chemical link to create a chemical compound.
Electron- A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound).
