Lesson Title:
Today we are learning about
What is covalent bonding?
Remember to check for PROGRESSFocus on Knowledge, Skills and Understanding
Success Criteria:
You will show your learning by...
When atoms share pairs of electrons, they form covalent bonds. These bonds between atoms are strong.
Covalently bonded substances may consist of small molecules.
Students should be able to recognise common substances that consist of small molecules from their chemical formula.
Some covalently bonded substances have very large molecules, such as polymers.
Some covalently bonded substances have giant covalent structures, such as diamond and silicon dioxide.
The covalent bonds in molecules and giant structures can be represented in the following forms: using dot-and-cross diagram, ball-and-stick diagram or displayed formula)
Polymers can be represented using displayed formulae, where n is a large number.
Students should be able to draw dot and cross diagrams for the molecules of hydrogen, chlorine, oxygen, nitrogen, hydrogen chloride, water, ammonia and methane
Students should be able to represent the covalent bonds in small molecules, in the repeating units of polymers and in part of giant covalent structures, using a line to represent a single bond
Students should be able to describe the limitations of using dot and cross, ball and stick, two and three-dimensional diagrams to represent molecules or giant structures
Students should be able to deduce the molecular formula of a substance from a given model or diagram in these forms showing the atoms and bonds in the molecule.

Keywords:
Giant covalent
: contain a lot of non-metal atoms, each joined to adjacent atoms by covalent bonds. The atoms are usually arranged into giant regular
(1)
Simple molecule
: Simple molecules contain only a few atoms held together by covalent bonds.
(1)
Molecule
: A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
(1)
Covalent bond
: A chemical bond formed between non-metal atoms, which combine together by sharing electrons.

How are polymers commonly represented?
Polymers can be represented using displayed formulae, where n is a large number.
Draw dot and cross diagrams for the molecules of hydrogen, chlorine, oxygen, nitrogen, hydrogen chloride, water, ammonia and methane look like?
How would you draw a single covalent bond?
single line between atoms
What are the limitations of using dot and cross, ball and stick, 2D and 3D diagrams to represent substances?
dot and cross, ball and stick do not show orginatation in space.
