Answer:

Ionic bond

Explanation:

The main component of quicklime is calcium oxide, whose chemical formula is CaO.

Ca is a metal with 2 electrons in its valence shell.

O is a nonmetal with 6 electrons in its valence shell.

Ca and O form a ionic bond, in which Ca loses 2 electrons and O wins 2 electrons, so that both obey the octet rule.
