An electron repels a(n) ______.

Explanation:
Like charges repel. An electron has a negative charge, so it repels another negatively charged particle—a fellow electron. Protons are positively charged, so they attract electrons rather than repel them. A neutron has no electric charge, so there’s no electrostatic repulsion with an electron. A positron carries positive charge and would attract an electron (and can annihilate it). So the repelled particle in this case is another electron.
