The covalent bond
In this lesson, you will be learning about how a covalent bond is formed using Valence Bond Theory, and how sigma, pi and dative bonds are formed.
Giant covalent structure
In this lesson, you will be learning about what makes a giant covalent structure, factor affecting strength of covalent bonds and how to answer melting or boiling point questions.
Dot-and-cross diagrams
In this lesson, you will be learning about how to draw dot-and-cross diagrams for different species.
Shapes of molecules
In this lesson, you will be learning about what Valence Shell Electron Pair Repulsion (VSEPR) Theory is, and the different molecular shapes.
Bond angles
In this lesson, you will be learning about how to use VSEPR Theory to explain differences in bond angles between different species.
Polarisation of ionic bond
In this lesson, you will be learning about how polarisation of ionic bond can lead to certain compounds adopting significant covalent character.
Polarity
In this lesson, you will be learning about what polarity is and how to determine whether a molecule is polar or non-polar.
