Simple Molecules And Covalent Bonds
Bayani Gaba-gaba
The oxygen you breathe, the water you drink and the methane that heats your food are all held together not by transferring electrons but by sharing them. This sharing creates the covalent bond, the glue of most non-metal compounds and the basis of all living matter.
In this lesson you will learn how a covalent bond forms when atoms share a pair of electrons, how to show this with simple diagrams, and how shared pairs build up familiar molecules such as hydrogen, water, methane and carbon dioxide.
Manufura
- State that a covalent bond is formed when a pair of electrons is shared between two atoms leading to noble gas electronic configurations.
- Describe the formation of covalent bonds in simple molecules, including H₂, Cl₂, H₂O, CH₄, NH₃ and HCl. Use dot-and-cross diagrams to show the electronic configurations in these and similar molecules.
- Describe in terms of structure and bonding the properties of simple molecular compounds: (a) low melting points and boiling points (b) poor electrical conductivity.
- [Supplement] Describe the formation of covalent bonds in simple molecules, including CH OH, C H , O , 3 2 4 2 CO and N . Use dot-and-cross diagrams to 2 2 show the electronic configurations in these and similar molecules.
- [Supplement] Explain in terms of structure and bonding the properties of simple molecular compounds: (a) low melting points and boiling points in terms of weak intermolecular forces (specific types of intermolecular forces are not required) (b) poor electrical conductivity.
