CHEMISTRY MANIAC

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.
• There is about 1/2 lb or 250 g of salt (NaCl) in the average adult human body

• A pure element can take many forms. For example, diamond and graphite both are forms of pure carbon.
• The chemical name for water (H2O) is dihydrogen monoxide.
• The only letter that doesn't appear on the periodic table is J.
• 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.
• Helium balloons float because helium is lighter than air.
• Bee stings are acidic while wasp stings are alkaline.
• Dry ice is the solid form of carbon dioxide, CO2.
• Liquid air has a bluish tint, similar to water.
