Not in a state of balance; uneven or unequal in distribution or proportion.
The team's performance was imbalanced, leading to a loss in the final match.

Imbalanced is formed from "in-" (meaning not) and "balanced" (from the root "balance" which comes from Latin "bilanx", meaning having two scales). The word describes a state of not being in balance or equilibrium.
Think of 'not' being in a state of 'balance' — that's why imbalanced means something is not balanced.
