Sense: adjective/1
Unbalanced is the most common form and overlaps with imbalanced for diets, distributions, and systems, but unbalanced also reaches into informal talk about a person's mental state ('he seemed mentally unbalanced'), where imbalanced sounds clinical and is usually avoided. Uneven is broader and more everyday: it covers both physical surfaces (an uneven floor) and unequal distribution (uneven workload), without the technical or formal flavour that imbalanced carries. Lopsided emphasises visible one-sidedness — a lopsided score, a lopsided cake, a lopsided argument where one side dominates. Skewed says results, data, or perception have been pulled toward one direction, often unfairly ('the survey results were skewed by a small sample'). Use imbalanced when writing about diets, economies, ratios, and training programmes; use unbalanced or uneven in informal speech.

Etymology
Imbalanced was formed in English by adding the prefix im- (meaning 'not', a form of in- used before b, m, and p) to the adjective balanced. The verb balance comes from Old French balance, from late Latin bilancia, built from bi- ('two') and lanx ('plate' or 'scale-pan'), referring to a two-plate weighing scale. So imbalanced literally pictures two scale-pans that fail to settle level. The form has been in use since the 1800s alongside the older and slightly more common 'unbalanced.'
