As a material scientist with a focus on the electrical properties of materials, I can provide you with an in-depth explanation of why metals conduct electricity in their solid state.
Metals are unique among solid materials due to their atomic structure and the nature of the chemical bonds that hold them together. The atoms in a metal are arranged in a crystal lattice, which is a highly ordered and repeating pattern. Each metal atom contributes one or more valence electrons, which are the outermost electrons that are involved in chemical bonding. In metals, these valence electrons are not tightly bound to their parent atoms; instead, they are free to move throughout the entire structure of the metal.
This phenomenon is known as the "sea of electrons" model. The valence electrons in a metal are delocalized and can move freely within the metal lattice. When an electric potential difference, or voltage, is applied across a piece of metal, these free electrons are influenced by the electric field and begin to move in a directed manner. This movement of electrons constitutes an electric current.
The ability of metals to conduct electricity is a direct result of the presence of these free electrons. The conductivity of a metal is determined by several factors, including the number of free electrons available, the structure of the metal lattice, and the temperature. Metals with a higher density of free electrons will generally have greater electrical conductivity.
It's important to note that not all solids conduct electricity. Covalent and ionic solids, for example, do not have free electrons in the same way that metals do. In covalent solids, atoms are bonded together by sharing electrons, and these electrons are localized between specific pairs of atoms. In ionic solids, atoms are bonded together by the electrostatic attraction between oppositely charged ions. In both cases, the electrons are not free to move throughout the material, and thus, these types of solids are poor conductors of electricity.
The electrical conductivity of metals can be further enhanced by refining the metal to reduce impurities and by alloying it with other metals to improve the metal's structure and electron mobility. Additionally, the conductivity of metals decreases with increasing temperature due to increased lattice vibrations that scatter the electrons.
In summary, metals conduct electricity in their solid state because they possess a unique atomic structure that allows for the presence of free electrons. These electrons can move freely within the metal lattice and respond to an applied electric field, resulting in the flow of electric current. The conductivity of metals is influenced by factors such as the number of free electrons, the metal's lattice structure, and temperature.

Metal atoms have outer electrons which are not tied to any one atom. These electrons can move freely within the structure of a metal when an electric current is applied. There are no such free electrons in covalent or ionic solids, so electrons can't flow through them - they are non-conductors.
