Oxygen is an element, it does not have elements. Temperature is not something to have elements or components, it is merely a measure of the average kinetic energy of molecular motion in a material (solid, liquid, or gas).
Oxygen
At room temperature, oxygen is a gas.
hydrogen and oxygen
The three elements that exist in the gaseous state at room temperature are helium, nitrogen, and oxygen.
most of the elements are solids at room temperature.
Carbon, oxygen, and hydrogen are all nonmetal elements.
Zinc and mercury are solids at room temperature, whereas oxygen and bromine are gases.
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
At room temperature: Chlorine: gas Helium: gas Hydrogen: gas Oxygen: gas
period 2. The elements are nitrogen, oxygen, fluorine and neon.
Oxygen differs from the other elements in the oxygen group (sulfur, selenium, tellurium, and polonium) in terms of its physical and chemical properties. Oxygen is a colorless and odorless gas at room temperature, while the other elements are solids. Additionally, oxygen is highly reactive and forms oxides readily, whereas the other elements have different chemical behaviors and may not readily form oxides.
Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
