Oxygen is necessary for respiration, and is present in everything from sugar to rust to fat, but is toxic when pure. O is element #8, and has a charge of -2. (And rarely, a charge of -1 when it forms peroxide ions). O has an electronegativity of 3.44, making it the second most electronegative element. At STP, O has a density of 1.429 g/L. O melts at 54.8 K and boils at 90.188 K. An active gas, Oxygen makes up 1/5 of the Earth's atmosphere. This gas is fairly common in the universe.
