type Os raft number is 15.9994. A way of finding an chemical elements mass number is to add the number of protons or electrons (the number of protons and electrons in an atom is equal) by the number of neutrons.
Oxygen is in the daily table group 16, (the Chalcogen family) which consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium, (Te), and polonium (Po.)
Oxygen is in period 2 of the periodic table.
Oxygens state in room temperature is gas.
Two physiological properties that distinguish oxygen from all other elements are its thaw signal and boiling point. An elements boiling point is unique and never the same as another elements melting point and boiling point. Oxygens melting point is 54.36 K or -218.79 °C and its boiling point is 90.20 K or -182.95 °C.
Oxygens slow-wittedness is 1.429g/L at 273K or 0.15 °C.
Oxygen is more ordinarily found as a compound rather than element. Oxygen is a very reactive element and it is not often found uncombined. It is probably easier to find an oxygen compound than an oxygen element. on that point are probably more compounds with oxygen than all other element.
There are many oxygen compounds worry carbon dioxide, carbon monoxide, magnesium oxide, sulfur oxide, nitrous oxide, rust, etc
There are many uses for oxygen like the ozone layer, combustion, and liquid oxygen, and the most important use of oxygen is breathing.
Oxygen has a charge of -2 when it reacts. Oxygen has 8 electrons, 2 of which is on the s orbital, and the other 6 in the p orbital and to puff it stable when it reacts, it needs 2 more electrons. Therefore it has a -2 charge when it reacts because when it reacts it takes 2 electrons from the other element, making it have 8 protons and 10 electrons. So 8 subtracted by 10 equals -2.If you destiny to get a full essay, order it on our website: Orderessay
