Answer:
It is the energy the ions absorb when they form a crystalline compound.
Explanation:
Lattice energy is the energy released upon the formation of a crystal lattice structure.
Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.
<h3>What kinds of bonds exist?</h3>
- Covalent bonds: These are formed between nonmetals and electrons by sharing electrons.
- Ionic bonds: These are formed between metals, which lose electrons, and nonmetals, which gain electrons.
- Metallic bonds: There are formed between metals. Electrons are delocalized in a cloud.
Water, H₂O, is a molecule made of 2 nonmetals: oxygen and hydrogen. The bonds that hold water molecules together are due to shared electrons, and known as covalent bonds.
