What matter type is oxygen?
gas
Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.
Is O2 aqueous or solid?
Oxygen is an element that can be a solid, liquid or gas depending on its temperature and pressure. In the atmosphere it is found as a gas, more specifically, a diatomic gas.
Is oxygen a gas?
Oxygen is a chemical element with an atomic number of 8 (it has eight protons in its nucleus). Oxygen forms a chemical compound (O2) of two atoms which is a colorless gas at normal temperatures and pressures. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive.
What’s the difference between oxygen and O2?
The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.
What Colour is solid oxygen?
Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.
Is O2 the same as oxygen?
Why is oxygen written as O2? The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.
What’s the difference between oxygen and oxygen gas?
The main difference is that oxygen is an element with the symbol O and oxygen gas is a molecule with the symbol O2.
What is the name of oxygen?
dioxygen
Oxygen is the chemical element with the symbol O and atomic number 8. 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.
What is the Colour of oxygen?
red

Which is the state of matter of oxygen?
All matter exists as either a solid, liquid, gas or plasma. This is called it’s ‘State Of Matter’. Oxygen exists as a gas. Wiki User
What is the normal melting point of oxygen?
The normal melting point of oxygen is -218°C; its normal boiling point is -189°C. Oxygen is a gas at room temperature. If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature.
Is the state of matter a solid or a liquid?
All matter exists as either a solid, liquid, gas or plasma. This is called it’s ‘State Of Matter’. Oxygen exists as a gas.
What are the properties of the three states of matter?
In daily life, four states of matter are visible: solid, liquid, gas, and plasma. There are three states of matter. The properties of solid, liquid, and gas are mentioned below. The 3 states of matter examples are wood, gold, water, Nitrogen, Oxygen. Solid, Liquid gas are three characters by which life is surrounded.
