  Let $F$ be a field with at least three elements and $G$ a locally finite
group. This paper aims to show that if either $F$ is algebraically closed or
the characteristic of $F$ is positive, then an element in the group algebra
$FG$ is a product of unipotent elements if, and only if, it? lies in the first
derived subgroup of the unit group of $FG$. In addition, it? is a product of at
most three unipotent elements.
  Moreover, we explore some crucial properties satisfied by certain algebras
like the connection between unipotent elements of index 2 and commutators as
well as we investigate the unipotent radical of a group algebra by showing that
the group algebra of a finite group over an infinite field cannot have a
unipotent maximal subgroup. In particular, we apply these results to twisted
group algebras.
