Are all abelian groups normal?

Excuse me, but I'm a bit confused about the concept of abelian groups and their normality. Could you please clarify if all abelian groups are inherently normal, or is there a specific condition or context in which this assertion holds true? I understand that abelian groups possess the commutative property, but I'm not entirely sure how this relates to the concept of normality in group theory. Your insights would be greatly appreciated. Are all abelian groups normal?

Cyclic groups, by definition, possess a unique characteristic that sets them apart from other groups in algebra. They are inherently Abelian, meaning that the operation of group multiplication is commutative within them.

The character table, a vital tool in the study of groups, takes on a particular form in Abelian groups. Instead of involving intricate relationships between multiple elements, the character table of an Abelian group simply involves powers of a single element, known as a group generator.

However, the converse is not always true. An Abelian group, while exhibiting the commutative property, does not necessarily follow a cyclic structure. This distinction underscores the complexity and diversity within the realm of group theory.

One notable aspect of Abelian groups lies in their subgroups. Unlike non-Abelian groups, where subgroups can exhibit varied behaviors, all subgroups of an Abelian group are inherently normal. This property simplifies the study of Abelian groups and their structures.
