Three interesting facts about me
When I was in high school I learned how to say you’re welcome.I don’t like thinking about noses and kneecaps.I think sunflowers are the creepiest thing in the world.When I was a kid I used to do sketch shows I would do this one reoccurring show where I played a husband and my wife was a broomstick and her name was Georgina.I never laugh when other people are laughing.
Oxygen is paramagnetic, which means it is weakly attracted to a magnet but doesn't retain permanent magnetism.Oxygen supports combustion. However, it is not truly flammable! It is considered an oxidizer.A single atom of oxygen usually has an oxidation number of -2. Singlet oxygen may be found in the upper atmosphere. Ozone, O 3, is another form of pure oxygen. Atomic oxygen, which is also called "singlet oxygen" does occur in nature, although the ion readily bonds to other elements. Oxygen gas normally is the divalent molecule O 2.The atoms readily gain electrons and form covalent chemical bonds. The solid form is brittle rather than malleable or ductile. Oxygen is a nonmetal. It has low thermal and electrical conductivity, but high electronegativity and ionization energy.Liquid and solid oxygen is pale blue. At lower temperatures and higher pressures, oxygen changes its appearance from blue monoclinic crystals to orange, red, black, and even a metallic appearance.Oxygen gas is colorless, odorless, and tasteless. It's usually purified by fractional distillation of liquefied air, but the element is found in many compounds, such as water, silica, and carbon dioxide.Symptoms of oxygen poisoning include vision loss, coughing, muscle twitching, and seizures. At normal pressure, oxygen poisoning occurs when the gas exceeds 50%. Plant photosynthesis drives the oxygen cycle, maintaining it around 21% in air. While the gas is essential for life, too much of it can be toxic or lethal.
Animals and plants require oxygen for respiration.
