what is a chemical bond
Answers

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. This attraction can occur through the sharing or transfer of electrons, resulting in different types of bonds. The primary types of chemical bonds include:
1. **Covalent Bonds**: These occur when two atoms share one or more pairs of electrons. This type of bond often forms between nonmetal atoms. Molecules like water (H₂O) and methane (CH₄) are examples of substances with covalent bonds.
2. **Ionic Bonds**: Ionic bonds form when one atom transfers one or more electrons to another atom, resulting in the formation of positively and negatively charged ions. The electrostatic attraction between these oppositely charged ions holds them together. Common examples include sodium chloride (NaCl).
3. **Metallic Bonds**: In metallic bonds, electrons are not shared or transferred in the same way as in covalent or ionic bonds. Instead, metals share a "sea of electrons" that are free to move around, which contributes to properties such as electrical conductivity and malleability.
These bonds structure the arrangement of atoms in molecules and solids, determining the physical and chemical properties of substances.
