Oxygen Element State At Room Temperature

Relative atomic mass the mass of an atom relative to that of.

Oxygen element state at room temperature.

That state of matter of an element may be predicted based on its phase diagram. Several of the nonmetals are gases in their elemental form. The most stable is astatine 210 with a half life of 8 1 hours. It is a member of the chalcogen group in the periodic table a highly reactive nonmetal and an oxidizing agent that readily forms oxides with most elements as well as with other compounds after hydrogen and helium oxygen is the third most abundant element in the universe by mass.

All of astatine s isotopes are short lived. Oxygen accounts for nearly half of the mass of the earth s crust two thirds of the mass of the human body and nine tenths of the mass of water. It is a liquid at 90 k and a solid at 54 k. A sample of the pure element has never been assembled because any macroscopic.

Its monatomic form h is the most abundant chemical substance in the universe constituting roughly 75 of all baryonic mass. The element oxygen is a gas at room temperature. Oxygen is the chemical element with the symbol o and atomic number 8. Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase.

You re breathing it in right now with a large portion of nitrogen too. Oxygen is the third most abundant element in the universe and makes up nearly 21 of the earth s atmosphere. While temperature is an easily controlled factor manipulating pressure is another way to cause a phase change. It is the rarest naturally occurring element in the earth s crust occurring only as the decay product of various heavier elements.

Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature. When pressure is controlled other pure elements may be found at room temperature. Its molecules contain two oxygen atoms. Gas oxygen o 2 is a gas at room temperature 273 k.

An example is the halogen element chlorine. Oxygen is vital for respiration which is the process that transfers energy from glucose to. Oxygen is a non metal element that is a gas at room temperature. With a standard atomic weight of circa 1 008 hydrogen is the lightest element on the periodic table.

Astatine is a chemical element with the symbol at and atomic number 85. The temperature at which the liquid gas phase change occurs. Other liquid elements.
