No,
but some of the gasses which make up air are elements (such as oxygen, nitrogen) are elements.
Oxygen itself is not an example of a mixture, but rather an element. However, air, which is a mixture of gases including oxygen, can be considered an example of a mixture.
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
One example of an element denser than air is sulfur hexafluoride (SF6). It is a colorless, odorless gas that is significantly denser than air, allowing it to be used in certain applications such as electrical insulation.
GAS
Oxygen is an element and so can not be a mixture by itself. It can be part of a mixture, for example in air.
element air . Air was an element in the old Greek system, it is not a chemical element.
Iron oxide (Fe2O3), also known as rust, is an example of an oxide of a transition element. It is a common compound that forms when iron reacts with oxygen in the presence of water or air.
One example of an element that fits this description is noble gas. Noble gases such as helium, neon, and argon do not react with water and can react violently with air when exposed to certain conditions.
"Evil air" and "frost-making stillness" are examples of personification, as they attribute human qualities to the air and stillness. This literary element allows readers to better understand and connect with the atmosphere being described.
One of the elements is gas, an example of that word is air that we breathe in everyday.
Oxygen is an everyday element that is typically in the gaseous phase under normal conditions. It is a key component of the air we breathe.
When an element burns in air, it reacts with oxygen to form a compound known as an oxide. The specific oxide formed depends on the element being burned. For example, when carbon burns, it forms carbon dioxide (CO2) and when magnesium burns, it forms magnesium oxide (MgO).
