Edexcel International GCSE Science – Chemistry separate Principles of Chemistry GCSE Chemistry – Covalent bonding and properties

Learning Objectives

-I can recall that covalent bonding occurs between 2 non-metals and a result of electrostatic attractions 
-I can represent the bonding in covalent compounds as a dot and cross diagram (diatomic molecules including hydrogen, oxygen, nitrogen, halogens and hydrogen halides  • inorganic molecules including water, ammonia and carbon dioxide  • organic molecules containing up to two carbon atoms, including methane, ethane, ethene and those containing halogen atoms.) 
-I can draw covalent compounds using lines to represent electron pairs 
-I can recall the names and formula of common covalent compounds
-I can recall that substances with a simple molecular structure are gases or liquids, or solids with low melting and boiling points
-I can use the term ‘intermolecular forces of attraction’ 
-I can recall that giant covalent structures are solids with high melting and boiling points 
-I can state that covalent compounds do not conduct electricity (other than water and graphite)
