Covalent Bonds
Covalent bonds are formed when two atoms share one or more pairs of electrons. This type of bonding usually occurs between nonmetal atoms. When two atoms share electrons, they are attracted to both nuclei, holding the atoms together and forming a molecule. Covalent bonds are characterized by the sharing of electrons, which allows both atoms to achieve a more stable electron configuration.
Properties of Covalent Bonds
- Covalent bonds are formed between nonmetal atoms.
- They involve the sharing of electrons.
- Covalent compounds tend to have relatively low melting and boiling points compared to ionic compounds.
- They can form single, double, or triple bonds, depending on the number of electron pairs being shared.
Study Guide
Here are some key points to remember about covalent bonds:
- Understand that covalent bonds are formed between nonmetal atoms.
- Learn the concept of electron sharing in covalent bonds.
- Be able to explain the difference between single, double, and triple covalent bonds.
- Understand the properties of covalent compounds, such as their relatively low melting and boiling points.
- Practice drawing Lewis dot structures for covalent molecules.
Remember to review examples of covalent compounds and their properties to reinforce your understanding of covalent bonds.
Good luck with your studies!
