Final answer:
Calcium oxide is an ionic compound, carbon forms covalent bonds, copper forms metallic bonding, and water is a covalent compound.
Step-by-step explanation:
The type of bonding for the elements or compounds mentioned are as follows:
A) Calcium Oxide: Calcium oxide (CaO) is an ionic compound. The calcium atom donates two electrons to the oxygen atom, forming an ionic bond.
B) Carbon: Carbon (C) forms covalent bonds. It shares electrons with other carbon atoms or with atoms of other elements to form stable covalent compounds.
C) Copper: Copper (Cu) is a metallic element and forms metallic bonding. In metallic bonding, the valence electrons are shared among all the atoms in the metal, resulting in a sea of electrons that hold the positive metal ions together.
D) Water: Water (H2O) is a covalent compound. The hydrogen atoms share electrons with the oxygen atom, forming covalent bonds. Water (H2O) - Water is a polar molecular compound with covalent bonds between hydrogen and oxygen atoms. However, the difference in electronegativity between H and O leads to a polar covalent bond, where the electrons are shared unequally.
