  • 1

    is composed of tiny indivisible particles

    matter

  • 2

    , meaning "indivisible".

    afomos

  • 3

    states that matter is neither be created nor destroyed in a chemical reaction, that is the total mass of the substances present before a chemical reaction is the same as the total mass after the reaction

    Law of Conservation of Mass (Law of Conservation of matter)

  • 4

    States that any sample of a compound will invariably have the same proportions by mass of its constituent's elements (constant).

    Law of Definite Composition

  • 5

    Discovered by John Dalton, this law states that a given quantity of an element may combine with different quantities of other elements may combine with different quantities of another element to form different compounds.

    Law of Multiple Proportions

  • 6

    are composed of small particles called atoms.

    Elements

  • 7

    of an element are identical, having the same properties such as mass, size and chemical properties.

    Atoms

  • 8

    are composed of atoms of at least two different elements, and the ratio of each element is an integer or a simple fraction.

    Compounds

  • 9

    results from the rearrangement of the atoms of reacting substances, giving new combinations of atoms.

    chemical reaction

  • 10

    were once thought to be indestructible.

    Atoms

  • 11

    It was instrumental in the discovery of the first subatomic particle, the electron.

    Cathode Ray Tube (CRT)

  • 12

    Presupposes that in the gold foil experiment, the alpha particles, which are positively charged, will pass through the atom smoothly in a straight line with little or no deflections.

    Plum-Pudding Model

  • 13

    Fits perfectly in describing hydrogen atoms. It cannot account for the mass of the next lightest element, helium.

    Nuclear Model

  • 14

    or proton number of an atom tells how many protons the atom has

    Atomic Number

  • 15

    tells the total number or protons and neutrons that the atoms has

    ORBITAL DIAGRAM

  • 29

    Electrons should enter the orbitals of a given sublevel singly with the same spin before any pairing is done

    HUND'S RULE OF MAXIMUM MULTIPLICITY

  • 30

    Two electrons occupying an orbital should have opposite spins. Note that the spin of an electron is either CLOCKWISE or COUNTERCLOCKWISE

    PAULI EXCLUSION PRINCIPLE

  • 31

    is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements

    Biotechnology

  • 36

    Most consumer products we use involve organic chemistry. Take the cosmetics industry as an example.

    Consumer Products

  • 37
