What are the chemical properties of oxygen gas ?
Oxygen Properties Priestley is generally credited with the discovery of oxygen, although Scheele also discovered it independently in 1774. Its atomic weight was used as a standard of comparison for each of the other elements until 1961 when the International Union of Pure and Applied Chemistry adopted carbon 12 as the new basis. Oxygen is an active, life-sustaining component of the atmosphere; making up 20.94% by volume or 23% by weight of the air we breathe. The word originated from the Greek word oxys and genes meaning sharp or acid and born respectively. Combining these Greek words together forms oxy genes that means acid forming. Atomic Number : 8 Mass Number : 15.9994 Electron Configuration : 1s22s22p4 Atomic Radius : 74 pm Ionic Radius : 140 (O2-) Characteristics of Oxygen Oxygen can exist in a number of physical forms. The most commonly found state of oxygen is the diatomic form and the triplet state. The diatomic form is molecular oxygen and the triplet state of commonly called
