Atoms are indivisible
I had a hard time finding this out.

Answer:
Explanation:
Atoms are held together by covalent bonds when they share electrons between themselves.
Covalent bonds are bonds that are formed between non-metals usually with a low electronegative difference between them. In this bond type, two non-metals donate electrons which are shared between the combining atoms and this makes them both like the corresponding noble gases. The shared electrons is what forms the covalent bonds.
An example of covalent bond is HCl, H₂S, SO₂, CO₂, O₂ etc
