How would you differentiate nucleophiles and electrophiles?

Nucleophile comes from “nucleus loving”, or “positive-charge loving”. A nucleophile is a reactant that provides electrons to form a new covalent bond.

Electrophile comes from “electron-loving”, or “negative-charge loving”. An electrophile is a species that accepts electrons to form a new covalent bond.
