Simple Covalent Bonding

Simple Covalent Bonding

What is Simple Covalent Bonding?

• Simple Covalent is between two non-metals and is when atoms SHARE electrons in order to gain full outer shells. Due to them sharing, rather than transferring they form molecules, for example water as shown on slide 1.
• The first slide shows the creation of the molecule, H2O due to the share of electrons/ covalent bonding, of oxygen and hydrogen. The oxygen needs two more electrons to gain a full outer shell whereas the hydrogen only needs one, hence why there are two hydrogens and only one oxygen.
• For covalent bonding, only draw the outer shell because if other shells are drawn and they accidentally overlap, you will lose marks!

Properties of Covalent Bonds

• Low melting and boiling points due to weak intermolecular forces.
• They can not conduct electricity.
• You can easily separate one WATER molecule from another (weak intermolecular forces) however you CAN NOT separate the hydrogen from the oxygen once it is covalently bonded.
