For example ,in H2 , two Hydrogen atoms are joined by a chemical bond called single bond as H-H
Similarly O2 has double bond between oxygen atoms as O=O.

Synthesis or combination chemical reaction.
Explanation:
Hello,
Chemical reactions are widely classified as synthesis or combination, decomposition and simple or double displacement. In this case, one states that when an atom forms a bond with another atom to build a linkage between them, a combination chemical reaction is happening because they are getting together in order to form a new compound.
