A compound consisting of a halogen and a more electropositive atom

#### Explanation:

A halide is a compound that consists of a halogen atom (any of the group 7 elements) and a positively charged, less electronegative atom.

For example, an alkyl halide is a compound that has the general formula:

$R - X$ where R is an arbitrary carbon chain, and X is a halogen (F, Cl, Br, I, etc.)

A metal halide consists of a metal (Group 1 or 2 element) and a halogen. Table salt (NaCl) is a good example of a metal halide.
