Hydrogen
Hydrogen is the most abundant atom in the universe! It is most commonly found as a gas (H2), in water (H2O), and also in all organic molecules. In my kitchen, hydrogen is found in all fruits and vegetables, all meats and beans, all grains, etc.
Helium
Helium is a colorless, tasteless, odorless, and non-toxic gas that is the second most abundant gas. It can be found in the air.
Boron
Boron is a mineral found in food and the environment. People take boron supplements as medicine for building strong bones (possibly found in the medicine cupboard) Fun Fact: Boron was used as a food preservative between 1870 and 1920, and during World Wars I and II.
Carbon
There are several allotropes of carbon, of which the best known are graphite and diamonds. Because of this carbon can be found in pencils.
Nitrogen
At room temperature, it is a gas of diatomic molecules and is colorless and odorless. Nitrogen is a common element in the universe, estimated at about seventh in total abundance. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins) and also in the nucleic acids (DNA and RNA).
Oxygen
Oxygen is an important part of the atmosphere, and is necessary to sustain most terrestrial life as it is used in respiration. However, it is too chemically reactive to remain a free element in Earth's atmosphere without being continuously replenished by the photosynthetic action of living organisms, which use the energy of sunlight to produce
elemental oxygen from water.
Fluorine
An extremely reactive and poisonous chemical element with atomic number 9.
Neon
The name neon is derived from the Greek word, νέον, neuter singular form of νέος [neos], meaning new. Neon is used in glow lamps, electron tubes,and cryogenic refrigeration.
Sodium
Sodium is the sixth most abundant element in the Earth's crust,it is present in soap and de-icing materials (popular in South Dakota) but it is most widely known for its presence in ordinary, every day table salt.
Magnesium
Magnesium is the fourth-most-common element in the Earth as a whole (behind iron, oxygen and silicon), making up 13% of the planet's mass and a large fraction of the planet's mantle. Magnesium is an important to our health and it is the eleventh most abundant element in the human body.
Aluminum
Aluminum is the third most abundant element and the most abundant metal in the earths crust, it is a silvery, soft, ductile metal that is revered for its light weight/ low density and it's ability to resist corrosion. Aluminum is used to make aluminum foil, present in most American kitchens.
Silicon
Silicon is a tetravalent metalloid and is distributed mainly by sand and dust.
Phosphorus
Fun Fact: The first form of elemental phosphorus to be produced (white phosphorus, in 1669) emits a faint glow upon exposure to oxygen – hence its name given from Greek mythology, Φωσφόρος meaning "light-bearer" (Latin Lucifer), referring to the "Morning Star", the planet Venus. The term "phosphorescence", meaning glow after illumination, originally derives from this property of phosphorus, although this word has since been used for a different physical process that produces a glow. Phosphorus can be found in matches because of its flamable reaction when exposed to oxygen.
Sulfur
Sulfur occurs naturally as the pure element (native sulfur) and as sulfide and sulfate minerals. Elemental sulfur crystals are commonly sought after by mineral collectors for their distinct, brightly colored polyhedron shapes.
Chlorine
Chlorine is in the halogen group (17) and is the second lightest halogen following fluorine. The element is a yellow-green gas under standard conditions, where it forms diatomic molecules. Free chlorine is rare on Earth, and is usually a result of direct or indirect oxidation by oxygen.
Argon
Argon is the third most common gas in the Earth's atmosphere, at 0.93% (9,300 ppm), making it approximately 23.8 times as abundant as the next most common atmospheric gas, carbon dioxide (390 ppm), and more than 500 times as abundant as the next most common noble gas, neon (18 ppm). Nearly all of this argon is radiogenic argon-40 derived from the decay of potassium-40 in the Earth's crust. In the universe, argon-36 is by far the most common argon isotope, being the preferred argon isotope produced by stellar nucleosynthesis in supernovas.
