Calcium hydroxide (Ca(OH)2) does not have both covalent and ionic bonding. It is an ionic compound, which means that its chemical bond is formed by the electrostatic attraction between positively and negatively charged ions.

In calcium hydroxide, calcium (Ca) loses two electrons to become Ca2+ cation, while hydroxide (OH-) gains an electron to become O2- anion. These ions are then attracted to each other to form an ionic bond.

Covalent bonding occurs when atoms share electrons to form a molecule, while ionic bonding occurs when electrons are transferred from one atom to another to form positively and negatively charged ions.
