The Periodic Table of Elements: Becka and Jess Style. =)

By: Rebekah and Jess

The History of the Periodic Table....

Antoine Lavoiser---compiled a list of 23 elements (the ones known at that time- late 1790s).

John Newlands--proposed an organization scheme for the elements.

Lothar Meyer-- demonstrated a connection between atomic mass and elemental properties.

Dmitri Mendeleev- organized the elements into the first periodic table.

Henry Moseley-arrranged the elements by atomic mass.

The Modern Periodic Table

Groups...The boxes arranged in order of increasing atomic number into a series of columns (GROUPS) or families


The rows of boxes are called periods.

Valence electrons- electrons in outermost orbitals/ determine chemical properties of element

Orbitals-describe electrons probable location (orbitals s,p,d,f).



Atomic Radius- half the distance between nuclei of identical atoms that are chemically bonded together.

trends within groups--atomic radii decrease as you move down a group.

trends within periods--decrease in atomic radii as you move left to right.

Ionic Radius-is a measure of the size of an ion in a crystal lattice

trends within groups--gradual increase in ionic size, going down.

trends within periods-- the size of the positive ions gradually decrease from left to right.

Ionization Energy-energy required to remove an electron from a gaseous atom.

trends within groups--first ionization energies generally decrease as you move down.

trends within periods-- first ionization energies generally increase as you move left to right.

Electronegativity- indicates relative ability of its atoms to attract electrons in a chemical bond.

trends within periods-- icreases as you move left to right.  

trends within groups-- decreases as you move down

The Lanthanide Elements


Lanthenum is the first of the lanthanide series. It Lanthanum is one of the rare earth elements used to make carbon arc lights which are used in the motion picture industry for studio lighting and projector lights. Lanthanum also makes up about 25% of Misch metal, a material that is used to make flints for lighters. Lanthana  is used to make the glass used in camera lenses and in other special glasses.


Cerium is the second element in the Lanthanide group. It is found in allanite, monazite, bastanite, cerite, and samarskite. It is used on pyrophoric alloys in cigarette lighters.


Praseodyminumis the 59th element on the periodic table. It is the third lanthanide element. Praseodyminum is widely used as a core materal for carbon arcs used by the motion picture industry for studio lighting and projection. Some of the salts are even used to color glasses.


Didymium, of which neodymium is a component, is used for coloring glass to make welders' goggles. Neodymium salts are also used for colorant for enamels.


Promethium could be used to make a nuclear powered battery. This type of battery would use the beta particles emitted by the decay of promethium to make a phosphor give off light. This light would then be converted into electricity by a device similar to a solar cell. It is expected that this type of battery could provide power for five years.


Samarium oxide has been used in optical glass ro absorb the infrared. samarium is also used in carbon-arc lighting in the motion picture industry.


Europium is the most reactive of the rare earth elements. There are no commercial applications for europium metal, although it has been used to dope some types of plastics to make lasers. Since it is a good absorber of neutrons, europium is being studied for use in nuclear reactors.Europium oxide, one of europium's compounds, is widely used as a red phosphor in television sets and as an activator for yttrium-based phosphors.


Gadolinium has the greatest ability to capture thermal neutrons of all known elements and can be used as control rods for nuclear reactors.Gadolinium can be combined with yttrium to form garnets that have applications in microwave technology.


Terbium is used to dope some types of solid-state devices and, along with zirconium dioxide as a crystal stabilizer in fuel cells that operate at high temperatures.Sodium terbium borate, a terbium compound, is used to make laser light.


There are no commercial applications for dysprosium. Since it easily absorbs neutrons and has a high melting point, dysprosium might be alloyed with steel for use in nuclear reactors. When combined with vanadium and other rare earth elements, dysprosium is used as a laser material.


Holmium has no commercial applications, although it has unusual magnetic properties that could be exploited in the future.

Holmium forms no commercially important compounds. Some of holmium's compounds include: holmium oxide holmium fluoride  and holmium iodide.


Erbium is alloyed with vanadium to make it softer and easier to shape. Erbium is added to fiber optic cables as a doping agent where it is used as a signal amplifier. Erbium also has some uses in the nuclear power industry.


Thulium is the least abundant of the naturally occurring rare earth elements. Metallic thulium is relatively expensive and has only recently become available. It currently has no commercial applications, although one of its isotopes, thulium-169, could be used as a radiation source for portable X-ray machines.


Ytterbium has few uses. It can be alloyed with stainless steel to improve some of its mechanical properties and used as a doping agent in fiber optic cable where it can be used as an amplifier. One of ytterbium's isotopes is being considered as a radiation source for portable X-ray machines.
