        Have 4 valence electrons. Includes metals, nonmetals and a metalloid.
        
        Have 3 valence electrons. Includes a metalloid (Boron) with everything else being metals.
        
        Most have 1 or 2 valence electrons. Combine chemically with oxygen to form compounds called oxides.
        
        Less reactive than alkali metals. Have 2 valence electrons.
        
        Have a single electron in their outermost level
        Most reactive metals; react violently with water.
  - - - Relied on the elements being arranged in order of increasing atomic mass, with every eighth element having similar properties to that of the first element. It is compared to the octaves found in music. It failed because it could only apply up until calcium. New elements being discovered also disproved this table.
    - - Based on the belief that the atomic mass of an element was the most fundamental property in classifying elements. It included vacant spaces for elements that have yet to be discovered. The elements were arranged in increasing order of atomic masses and their properties. It failed since hydrogen couldn't be given a fixed position on the table as well as some elements being in the same group but having different properties.
    - - Relied on triad groups of elements, with similar properties, whose middle element's atomic mass was the mean of the atomic mass of the two other elements. It failed since only a few triads followed the rule.
    - - Based on the Modern Periodic Law which states that the chemical and physical properties of elements are a periodic function of their atomic number. This table has multiple versions with the long form being most common. No limitations have been met, yet.
  - - - This is the energy required to remove an electron from an atom.
    - - This is the amount of energy released when an atom gains an electron.
    - - This is the one-half the distance between the nuclei of two atoms bonded together (called the inter-atomic bonded distance).
    - - This the ability of an atom in a compound to attract additional electrons towards itself.
    - - How much an element's properties is similar to that of a metal.
- - - - Proton (+ charge)
      - Electron (- charge)
      - Neutron (Has no charge)
    - - A collection of positively charged protons and neutrons which have a neutral charge at the center of the atom.
    - - The space around the nucleus of an atom where the electrons stay in.
  - - - It states that an atom consists of a positively charged sphere, with electrons spread within the sphere.
    - - It states that atoms have a positively charged center called the nucleus and that electrons revolve around the nucleus in a circular path.
    - - It states that compounds are composed of more than one element and that a chemical reaction involves only the separation, combination or rearrangements of atoms.
    - - It states that atoms have a third particle that is not affected by positive or negative charges. This particle is now called the neutron.
    - - It states that all matter consists of very small indivisible particles called atoms.
