Chemical Bonding

# Learning objectives

Be able to describe ionic bonding{.info}

Be able to describe covalent bonding{.info}

Be able to represent bonding using chemical equations{.info}

# Ionic Bonding{.objective .objective1}

In this section, the formation of ionic bonds will be outlined. Ionic bonding will be described as elements either losing or gaining electrons and in doing so, will develop an ionic charge. The ionic charge will cause ionic lattices to be formed between ions with opposing charges: e.g. Sodium + Chlorine => Sodium Chloride.

Students will be asked to explore the scene and observe the reaction between Sodium and Chlorine. They will be asked to identify evidence of ions and ionic bonds being formed.

# Covalent Bonding{.objective .objective2}

This section will examine the formation of covalent bonds between elements that share electrons from their outer shells. Some elements tend to gain electrons, and some will lose electrons to achieve a stable full outer shell. Doing so leads to these elements sharing electrons and forming bonds. E.g. Water being formed between Hydrogen and Oxygen.

Students will be asked to explore the scene and observe the reaction between Hydrogen and Oxygen. They will be asked to describe the properties of water as a small covalent molecule.

# Ionic Compounds and Covalent Molecules{.objective .objective3}

In this section, a description of ionic lattices will be provided, and students can learn how opposing ions form a tight regular formation made up of negative and positive ions. Here, a description of various covalent molecules will be provided too, along with a description of how sharing of electrons leads to the naturally occurring variations of molecules, whether it is an element of a compound.

Students will be asked to explore the modelled substances and compare them to each other. They will be asked to describe the similarities and differences between ionic lattices and covalent structures.
