Here are some interesting facts related to chemistry:- 1)The only elements that are liquid at room temperature are bromine and mercury. However, you can melt gallium by holding a lump in the warmth of your hand. 2)Unlike many substances, water expands as it freezes. An ice cube takes up about 9% more volume than the water used to make it. 3)If you pour a handful of salt into a full glass of water, the water level will actually go down rather than overflowing the glass. 4)There is about 1/2 lb or 250 g of salt (NaCl) in the average adult human body. 5)A pure element can take many forms. For example, diamond and graphite both are forms of pure carbon. 6)The only letter that doesn`t appear on the periodic table is " J" . 7)Lightning strikes produce O3, which is ozone, and strengthen the ozone layer of the atmosphere. 8)The only two non-silvery metals are gold and copper. 9)Although oxygen gas is colorless, the liquid and solid forms of oxygen are blue. 10)The human body contains enough carbon to provide `lead` (which is really graphite) for about 9,000 pencils. 11)Hydrogen is the most abundant element in the universe, while oxygen is the most abundant element in the earth`s atmosphere, crust, and oceans (about 49.5%). 12)The rarest naturally-occurring element in the earth`s crust may be astatine. The entire crust appears to contain about 28 g of the element. 13)Hydrofluoric acid is so corrosive that it will dissolve glass. Although it is corrosive, hydrofluoric acid is considered to be a `weak acid`. 14)One bucket full of water contains more atoms than there are bucketfuls of water in the Atlantic ocean. 15)Approximately 20% of the oxygen in the atmosphere was produced by the Amazon rainforest. 16)Helium balloons float because helium is lighter than air. 17)Bee stings are acidic while wasp stings are alkaline. 18)Hot peppers get their heat from a molecule called capsaicin. While the molecule acts as an irritant to mammals, including humans, birds lack the receptor responsible for the effect and are immune to the burning sensation from exposure. 19)Dry ice is the solid form of carbon dioxide, CO2. 20)Liquid air has a bluish tint, similar to water.

This is a collection of 10 fun and interesting basic chemistry facts. Chemistry is the study of matter and energy and the interactions between them. It is a physical science that is closely related to physics, which often shares the same definition. Chemistry traces its roots back to the ancient study of alchemy. Chemistry and alchemy are separate now, though alchemy still is practiced today. All matter is made up of the chemical elements, which are distinguished from each other by the numbers of protons they possess. The chemical elements are organized in order of increasing atomic number into the periodic table. The first element in the periodic table is hydrogen. Each element in the periodic table has a one or two letter symbol. The only letter in the English alphabet not used on the periodic table is J. The letter q only appears in the symbol for the placeholder name for element 114, ununquadium, which has the symbol Uuq. When element 114 is officially discovered, it will be given a new name. At room temperature, there are only two liquid elements. These are bromine and mercury. The IUPAC name for water, H2O, is dihydrogen monoxide. Most elements are metals and most metals are silver-colored or gray. The only non-silver metals are gold and copper. The discoverer of an element may give it a name. There are elements named for people (Mendelevium, Einsteinium), places (Californium, Americium) and other things. Although you may consider gold to be rare, there is enough gold in the Earth`s crust to cover the land surface of the planet knee-deep.

Chemistry is a fascinating science, full of unusual trivia! Here are some fun and interesting chemistry facts for you. The only elements that are liquid at room temperature are bromine and mercury. However, you can melt gallium by holding a lump in the warmth of your hand. Unlike many substances, water expands as it freezes. An ice cube takes up about 9% more volume than the water used to make it. If you pour a handful of salt into a full glass of water, the water level will actually go down rather than overflowing the glass.

Lightning strikes produce O3, which is ozone, and strengthen the ozone layer of the atmosphere. The only two non-silvery metals are gold and copper. Although oxygen gas is colorless, the liquid and solid forms of oxygen are blue. The human body contains enough carbon to provide `lead` (which is really graphite) for about 9,000 pencils. Hydrogen is the most abundant element in the universe, while oxygen is the most abundant element in the earth`s atmosphere, crust, and oceans (about 49.5%). The rarest naturally-occurring element in the earth`s crust may be astatine. The entire crust appears to contain about 28 g of the element. Hydrofluoric acid is so corrosive that it will dissolve glass. Although it is corrosive, hydrofluoric acid is considered to be a `weak acid`. One bucket full of water contains more atoms than there are bucketfuls of water in the Atlantic ocean. Approximately 20% of the oxygen in the atmosphere was produced by the Amazon rainforest.
