Summary:
- Compounds that form from two or more nonmetallic elements, such as carbon and hydrogen, are called covalent compounds.
- atoms of the different elements are held together in molecules by covalENT bonds.
- Covalent bonds are responsible for many of the properties of the compounds.
- Because valence electrons are shared in covalents, they have very different properties than ionic compounds.
- Many covalant compounds, especially those containing carbon and Hydrogen, burn easily.
- In contrast, many ionic compound do not burn.
