Germanium/ Ge
Element F is a metalloid solid.
Its existence and properties were predicted by Mendeleev when he left an empty space for this element on his table
calling it eka-silicon. Its existence was discovered 20 years later proving Mendeleev correct.
Radium/ Ra
Element L is a radioactive element in the group that was discovered by
Madame Curie.
Hydrogen/ H
Element M is a gas at standard conditions which has some chemical properties similar to the elements in
Group 1A and 7A. It is the major source of fuel in the sun and the most abundant element in the universe.
Bromine/ Br
Element N is a liquid at room temperature
Iodine/ I
Element O is a non-radioactive solid that has medicinal uses and is necessary in
the human diet for proper operation of the thyroid gland.
Fluorine/ F
Element P is the most chemically reactive of all of the non-
metal elements and has the highest value of electronegativity on the periodic table.
Chlorine/ Cl
Element Q is a gas at
room temperature and its compounds are used for water purification and is often used in swimming pools to kill
bacteria.
Sulfur/ S
Element R is a yellow non-metallic solid that has several allotropic forms. It is used commercially in the
manufacturing of sulfuric acid (a common laboratory acid) and is used to vulcanize rubber.
Silicon/ Si
Element S is a metalloid,
with a valley named after it, used in transistors and computer chips.
Aluminum/ Al
Element T has a relatively low density and is a
corrosion resistant metal, with a density of 2.7 g/cm3, that is often used in the manufacturing of ship and aircraft frames and parts. It is also the most abundant metal found in the earth's crust.
Copper/ Cu
Element U is an excellent conductor of heat and
electricity and is commonly used in the construction of electrical wiring and cookware.
Mercury/ Hg
Element V is the only metal that has a melting point below 25 degrees C and has an excellent coefficient of expansion that makes it ideal for use in temperature measuring devices.
Iron/ Fe
Element W is an easily oxidized metal that is produced in large quantities and is the
major component in steel.
Gold/ Au
Although once commonly used in US coins, element X has become too valuable and is now
used mostly in the manufacture of expensive jewelry.
Silver/ Ag
Element Y is less valuable than gold and is often used in
the manufacturing of mirrors and several of its compounds are used in photographic film.
Cadmium/ Cd
Element Z forms only one
species of cation (one charge only) and is commonly used in rechargeable batteries, when alloyed with nickel metal,
and control rods in nuclear reactors.
Plutonium/ Pu
Element AA is a man-made actinide fuel produced in nuclear reactors and the second atomic bomb dropped
on Nagasaki.
Mendelevium/ Md
Element AB is an actinide element named for the "father of the modern periodic table"
Arsenic/ As
Element AC
is a metalloid element used in the manufacturing of steel ball bearings and oxides of this elements will form a deadly
poison that has an odor of garlic.
Alkaline metals
element group of the most reactive metals. All of them
will react with chlorine to produce salts.
alkaline earth metals
This is also a relatively
reactive group of metals that are never found "free or uncombined" with other elements in nature.
Neon / Ne
Gas A is commonly used in advertising signs.
Helium/ He
Element B was first discovered on the sun and is widely
used in weather balloons.
Xenon/ Xe
Element C was used to make the first stable compounds of any element in this unreactive
group, and is being considered as a fuel in ion engines for deep space missions.
Argon/ Ar
Element D is the group member that is
present in significant amounts in air. It is the third most abundant element in air, and is also used as an inert gas in arc welding.
Nitrogen/ N
Element E forms a diatomic molecule and is the major constituent gas in the earth's atmosphere.
Its compounds are used extensively in the manufacturing of fertilizer and explosives.
Sodium/ Na
Element G is used as light source in street lamps and it is also a major
component of common table salt.
Lithium/ Li
Element H has the highest ionization energy value in the group and its compounds
are often used to treat depression.
Cesium/ Cs
Isotopes of element I are used in the atomic clock and has one of the lower
measured ionization energies in its group.
Calcium/ Ca
A compound of
element J is a major component of bones and teeth and is found abundantly in nature as carbonate compounds.
Magnesium/ Mg
Element K is commonly used in the manufacturing of lightweight aircraft frames because it has a very low density and
burns bright and hot in the presence of oxygen.
