What is the difference between ionic and covalent bonds?

Back

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

Front

What is electronegativity?

Back

The ability of an atom to attract electrons in a bond.

Front

What is a metallic bond?

Back

A bond formed by the attraction between positively charged metal ions and the electrons around them.

Front

What is a nonpolar covalent bond?

Back
