Question

What kind of bond holds together atoms within a molecule?

Answer 1

There are two main types of chemical bondsthat hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalentbonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond.

Answer 2

There is a force of attraction within the atoms which binds them in a molecule.

Explanation:

This force of attraction is the bond . These bonds are of three types.:-

1. Ionic bond:- This bond exists in between the ions of opposite charges i.e. positive and negative ions. It is formed by the losing and  gaining of electrons.
2. Covalent bond :- This bond is formed by the sharing of electrons.It is mostly formed by the elements which can neither gain or lose electrons.
3. Coordinate bond:- This bond is formed when one atom or a molecule donates its electron or a lone pair to another atom or a molecule.

Hence, It's actually a force of attraction that binds atoms in a molecule.
