Ionic and covalent bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically formed when one atom transfers electrons to another.

What is the charge of a sodium ion (Na+) after it loses an electron?

Back

The charge of a sodium ion (Na+) after it loses an electron is +1.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the formation of charged ions, while covalent bonds involve the sharing of electrons between atoms.
