FACTS

FACTS, DO YOU KNOW??

This is a collection of 10 fun and interesting basic chemistry facts.


1>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.

2>Chemistry traces its roots back to the ancient study of alchemy. Chemistry and alchemy are separate now, though alchemy still is practiced today.

3>All matter is made up of the chemical elements, which are distinguished from each other by the numbers of protons they possess.

4>The chemical elements are organized in order of increasing atomic number into the periodic table. The first element in the periodic table is hydrogen.

5>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.

6>At room temperature, there are only two liquid elements. These are bromine and mercury.

7>The IUPAC name for water, H2O, is dihydrogen monoxide.

8>Most elements are metals and most metals are silver-colored or gray. The only non-silver metals are gold and copper.

9>The discoverer of an element may give it a name. There are elements named for people (Mendelevium, Einsteinium), places (Californium, Americium) and other things.

10>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.
