Halides

Definition

Halides are compounds formed when halogens react with other elements, typically metals. They are often binary compounds where halogen atoms combine with less electronegative elements.

5 Must Know Facts For Your Next Test

1. Halides can form from reactions between halogens and both metals and nonmetals.
2. Common examples of halides include sodium chloride (NaCl), hydrogen fluoride (HF), and calcium fluoride (CaF2).
3. Halides are typically ionic in nature when formed with metals but can be covalent when formed with nonmetals.
4. Many halides are water-soluble, making them essential for various biological and industrial processes.
5. The reactivity of halogens decreases down the group, influencing the properties of their respective halides.
