Types of Bonding
Chemical Bonding
In this tutorial we will be briefly discussing the types of chemical bonds that you will encounter throughout the rest of the course.
Atoms of elements react by forming chemical bonds, this involves sharing or transferring electrons to achieve an electronic structure of a noble gas, which is stable. There are three main bonds you need to know about:
- Ionic Bonding
- Covalent Bonding
- Metallic Bonding
Ionic Bonding
When metal and non-metal atoms react, electrons are transferred from the metal to the non-metal. When the metal loses electrons to form positive ions. When the non-metal gains electrons, it forms negatively charged ions. The electrostatic force of attraction between the oppositely charged ions is known as ionic bonding.
Covalent Bonding
When two non-metal atoms react, electrons are shared between the atoms to achieve a more stable electronic structure. The bond formed when these electrons are shared is known as covalent bonding.
Metallic Bonding
In alloys and metallic elements, there are positive metal ions in a sea of delocalised electrons. The electrostatic force of attraction between the positive ion and the delocalised electrons is known as metallic bonding.
