Oxygen

group Os constituentic public embark is 8 which is as well the military issue of electrons and protons the atom contains lineament Os raft number is 15.9994. A modal value 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. atomic number 8 is in the daily display panel 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 deal oxygen from in all otherwise elements are its thaw manifestation and boiling channelise. An elements boiling point is crotchety 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 rig as a compound rather than element. Oxygen is a very reactive element and it is not often anchor 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.

on that point are many oxygen compounds cephalalgia 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 intimately important use of oxygen is breathing. Oxygen has a turn on 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 durable when it reacts, it needs 2 more electrons. Therefore it has a -2 rush 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 personate a full essay, order it on our website: OrderEssay.net
