Term
ionic bond
Definition
A bond between a metal cation and a non-metal anion

A bond in which a metal transfers valence electrons to a non-metal so the metal ends up with a positive charge and the non-metal ends up with a negative charge
Term
transfer
Definition
To move something from one place to another

More specifically, to move something from one atom to another atom
Term
cation
Definition
An atom which has lost electrons so that it has a positive charge
Term
