Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from a specific atom.

Front
