In general, the term atomic mass is preferred over atomic weight. Scientists usually do not refer to the actual mass of an atom in units with which we are familiar (units such as grams and milligrams). The reason is that the numbers needed are so small. The mass of a single atom of ...
O, a chemical element of group VI of Mendeleev’s periodic system. Atomic number, 8; atomic mass, 15.9994. Under normal conditions, oxygen is a colorless, tasteless, and odorless gas. It would be difficult to name another element that plays as important a role on earth as oxygen. ...
which were present as aerosol propellants in spray cans and as refrigerants, caused depletion of ozone in the stratosphere. This occurred because ultraviolet light also causes CFCs to decompose, producing atomic chlorine. The chlorine atoms react with ozone molecules, resulting in a net...
Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (except gases) weigh about 0.25 grams each, and the whole set...
By comparison, the density of air is about 1.29 grams per liter. Oxygen exists in three allotropic forms. Allotropes are forms of an element with different physical and chemical properties. The three allotropes of oxygen are normal oxygen, or diatomic oxygen, or dioxygen; nascent, atomic, ...
As an example, the actual mass of a proton is 1.6753 × 10 −24 g, or 0.000 000 000 000 000 000 000 001 675 3 grams. Numbers of this size are so inconvenient to work with that scientists have invented a special unit known as the atomic mass unit (abbreviation: amu) to state ...
