Ionic and covalent bonding

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 between a metal and a non-metal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, usually between non-metal atoms.

Define cation.

Back

A cation is an ion with a positive charge, formed when an atom loses one or more electrons.

Front

Define anion.

Back

An anion is an ion with a negative charge, formed when an atom gains one or more electrons.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond in which the electrons are shared unequally between the two atoms, resulting in a partial positive charge on one atom and a partial negative charge on the other.
