Periodic Table
Welcome to the beginning.
Akali metals
All 6 akali metals are highly reactive.Are less dense and have one loosely bound valance electron.They have the largest atomic radii in their period.

Akaline metals
These elements posses many traits of metals.They have 2 valance electrons that are not closely bounded and are easily lost.
Calcium shown below
Nonmetals
They are poor conductors and are very easily broken.They gain electrons easily and have no luster.
Sulfur shown below.
Transition metals
They are very hard and have a high boiling point.They posses the traits of metals.
Iron shown below
Metelloids
They posses traits of metals/nonmetals.There reactivity depends on properties of other metals in reaction.
Boron shown below
Noble gases
Not really reactive and have a valence shield(8 electrons).They have a low boil point.
Neon shown below
Halogens
Highly reactive with akali and akaline metals and have a really high electronegativities.
Flourine shown below
Metals
Are very dense and great conductors.Have a very high boiling point.Have a shiny appearance.
Copper shown below in wire form.
Lanthanoids
They have high melting and boiling points and react to air.Their color is a silverish whiteish.
Below is Cerium
Actinoids
All are radioactive materials and react with most nonmetals.They decay in air.
Below is plutonium.
Ionization energy
Ionization energy is the amount of energy it takes to remove an electron from a neutral atom.
Below is pic to explain.
Atomic radius
Is the size of an atom measured.
Below is the only picture i can find that explaines it better than me.
Electronegativity
Is the measure of the tendency of an atom to attract a bonding pair.
Below is image to explain.
