There are two kinds of electrical charge.
We call them 'positive' and 'negative' ... I guess nobody ever thought of better names.
One basic law of electric charges is:
Two of the same kind of charge repel each other.
One of each kind of charge attract each other.
Electrons all carry a negative charge.
So two electrons carry the SAME kind of charge, and so repel each other.
