An electron carries negative charge. It is an electron.

A sheep has mass, but it is a sheep.

When you see something like "the charge on a conductor is -1.0 μC" this says to you that the conductor is not neutral but has an excess of 6,241,509,074,460 electrons on it (give or take a few). You get that number by dividing the negative charge by the charge of one electron.
