  1. Oxygen :Kativa Wadley :Tech-6

  2. Atomic number Atomic number • The atomic number for oxygen is eight (8)

  3. Atomic Mass • The atomic mass for oxygen is (15.9994) Atom ic mass

  4. Symbol symbol • The symbol for oxygen is”o”

  5. History of oxygen • Oxygen had been produced by several chemists prior to its discovery in 1774, but they failed to recognize it as a distinct element. Joseph Priestley and Carl Wilhelm Scheele both independently discovered oxygen, but Priestly is usually given credit for the discovery. They were both able to produce oxygen by heating mercuric oxide (HgO). Priestley called the gas produced in his experiments 'dephlogisticated air' and Scheele called his 'fire air'. The name oxygen was created by Antoine Lavoisier who incorrectly believed that oxygen was necessary to form all acids.

  6. Appearance of oxygen • A new generation has adopted the design style of foreign high accuracy with all-round note oxygen appearance, In making oxygen foundation reply, increase the intensity, Raise the precision
