Physical And Chemical Properties Of Helium
Well it is partly true.
Physical and chemical properties of helium. Appearance (at stp) colourless gas The state of superfluid is called helium ii. The physical properties of helium are nothing but the characteristics that are seen without changing the substance into another.
Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. Helium is the second most abundant element in the universe, but here on earth, it's rather rare. Its boiling point is the lowest among all the elements.
Helium can be liquefied, but its condensation temperature is the lowest when compared to all the known substances. The fact that helium is inert and does not form compounds or react to any existing element is its chemical property….” its inability to undergo a change that alters its composition”.[“physical and chemical properties of matter” university of california davis] 'sun') is a chemical element with the symbol he and atomic number 2.
The main helium source in the world is a series of fields of natural gas in the united states. Most people guess that we extract helium from the air, but actually we dig it out of the ground. Argon is a chemical element in the eighteen group of the periodic table.
The boiling point for a gas is the temperature at which the gas changes to a liquid. In the modern periodic table, group 18 belongs to noble gases. It’s the second lightest element.
Helium has physical properties like density, boiling point, conductivity etc. Introduction to physical and chemical properties of noble gases. It is a noble gas and it is the third most abundant gas in earth’s atmosphere.
