Why does oxygen typically form two bonds?

Oxygen typically forms two bonds because it has six valence electrons and needs two more to complete an octet, so it shares two electrons through bonding to reach a full shell.

Think of an oxygen atom like a house that likes to have eight furniture pieces in the living room; it already has six chairs, so it needs two more to feel comfortable. Atoms share electrons when making bonds, so oxygen usually shares two electrons with one or two other atoms to get those missing pieces. Sometimes it shares both with one atom to make a double bond, like in oxygen gas where two oxygens share two pairs of electrons between them. Other times it makes two single bonds with two different atoms, like in water, where each hydrogen gives one electron to share with oxygen so oxygen ends up with eight electrons around it.

A common mistake is thinking oxygen always makes the same type of bond, when actually it can form single or double bonds depending on the partner atom and the molecular situation; the fix is to look at how many electrons each atom needs to complete an octet. Another misconception is imagining electrons as little balls that move from one atom to another instead of seeing bonds as shared pairs; it helps to draw Lewis structures to visualize shared electrons. Some people forget that oxygen can have expanded bonding in special cases like in molecules with formal charges, so remember to count electrons and check formal charges to find the correct structure.
