Helium is a colourless, odourless gas with an extremely low boiling point
Helium is an element that has physical properties. So far it has eluded efforts to make it react with anything else. It could thus be argued it does not have chemical properties other than it is very inert.
Helium atoms have the same physical properties regardless of whether they are found on the Sun or on Earth. The properties of an element, such as its atomic number and mass, remain constant regardless of its location. However, the environment in which helium atoms exist can affect their behavior, such as temperature and pressure differences, which could influence their physical interactions.
Well it is partly true. Helium has physical properties like density, boiling point, conductivity etc. But it has no chemical property.
Helium is an element a pure substance it is a chemical. It has properties eg it is a gas, it is colourless, it is odourless
the first property is gas emit lights and helium
No. This is because it is demonstrating the fact that it is less dense than the air. Density is a physical property. Therefore the helium balloon rising to the ceiling is not a chemical property, and instead a physical property.
helium is chemically inert and has no chemical properties
Helium is inert. There are no known compounds. It has no chemical properties.
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Temperature affects helium by changing its physical state. At higher temperatures, helium can transition from a liquid to a gas. Additionally, temperature can impact the behavior of helium gas, such as its diffusion rate or expansion properties.
Yes, liquid helium is a true substance. It is the liquid form of the element helium, which is a noble gas. At very low temperatures close to absolute zero, helium gas condenses to form liquid helium, exhibiting unique physical properties and behaviors.
Helium is a colorless, odorless, and tasteless gas at room temperature and pressure. It has a low boiling point of -268.9 degrees Celsius and a low density, making it lighter than air. Helium is also chemically inert, meaning it does not readily react with other elements.
