  1. 1ATOM: This is the smallest particle of matter. All matter is made up of atoms. An atom is like a tiny solar system. In the centre of the atom is the [blank_start]nucleus[blank_end] which is a cluster of [blank_start]protons[blank_end] ([blank_start]positively[blank_end] charged) and [blank_start]neutrons[blank_end] ([blank_start]no[blank_end] charge). Whirling at fantastic speeds around the [blank_start]nucleus[blank_end] are smaller and lighter particles called [blank_start]electrons[blank_end] ([blank_start]negatively[blank_end] charged).
    1. Anucleus
    2. Bprotons
    3. Cpositively
    4. Dneutrons
    5. Eno
    6. Fnucleus
    7. Gelectrons
    8. Hnegatively
  2. 2Each circle can only hold a certain number of [blank_start]electrons[blank_end] before it becomes full and stable. Thus:
    - Innermost circle (or shell) = [blank_start]2[blank_end]
    - Second circle (or shell) = [blank_start]8[blank_end]
    1. A2
    2. B8
    3. Celectrons
  3. 3the electrons in the [blank_start]outer[blank_end]most shell that take part in [blank_start]chemical bonding[blank_end].
    1. Achemical bonding
    2. Bouter
  4. 4A chemical element is a pure chemical substance consisting of one type of atom distinguished by its [blank_start]ATOMIC NUMBER[blank_end], which is the number of [blank_start]protons[blank_end] in its [blank_start]nucleus[blank_end].
    1. AATOMIC NUMBER
    2. Bprotons
    3. Cnucleus
  5. 5[blank_start]Molecule[blank_end] is formed when two or more atoms join together chemically e.g. Oxygen.
    1. AMolecule
  6. 6[blank_start]6[blank_end] electrons in Carbon
    1. A6
  7. 7[blank_start]8[blank_end] electrons in Oxygen
    1. A8
  8. 8Hydrogen: number of electron =[blank_start]1[blank_end], proton =[blank_start]1[blank_end], neutron = [blank_start]0[blank_end]
    1. A1
    2. B1
    3. C0
  9. 9When different elements join together they form a substance called a [blank_start]compound[blank_end]. Compounds are divided into [blank_start]two[blank_end] categories:
    1. Acompound
    2. Btwo
  10. 10- [blank_start]ORGANIC[blank_end] – complicated compounds containing several elements. One of the elements always contains [blank_start]carbon[blank_end] e.g. carbohydrates.
    - [blank_start]INORGANIC[blank_end] – small compounds e.g. water (H2O) and ammonia (NH3)
    1. AORGANIC
    2. Bcarbon
    3. CINORGANIC
