What do halogen atoms attach to to create alkyl halides?

Halogen atoms can attach to alkane hydrogens to create alkyl halides through a substitution reaction, where a hydrogen atom is replaced by a halogen atom. This reaction is often facilitated by a halogenating agent such as a halogen gas or a halogen-containing compound like N-halosuccinimide.

What type of compound is formed when halogen reacts with a metal?

When a halogen reacts with a metal, an ionic compound known as a metal halide is formed. In this type of compound, the metal atom loses electrons to the halogen atom, resulting in the formation of positive metal ions and negative halide ions that are held together by strong electrostatic forces.
