CHEMISTRY ADVANCED LEVEL FULL NOTES FORM 5 AND 6
Chemistry is the scientific study of the properties and behavior of matter.
CHEMISTRY STUDY NOTES ORDINARY LEVEL:- It is a natural science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.
In the scope of its subject, chemistry occupies an intermediate position between physics and biology.
It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.
Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are two types of chemical bonds:
1. primary chemical bonds e.g covalent bonds, in which atoms share one or more electron(s); ionic bonds, in which an atom donates one or more electrons to another atom to produce ions (cations and anions); metallic bonds and
2. secondary chemical bonds e.g. hydrogen bonds; Van der Waals force bonds, ion-ion interaction, ion-dipole interaction etc.
