Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among all the elements. Helium is the second lightest element and is the second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined.
It is a colorless, odorless inert gaseous element occurring in natural gas and with radioactive ores. It is less soluble in water than any other gas. The Physical and Chemical Properties are the characteristics of a substance, like Helium, which distinguishes it from any other substance.Most common substances exist as States of Matter as solids, liquids, gases and plasma.elium Properties-What are the Chemical Properties of Helium? What are the Chemical Properties of Helium? They are the characteristics that determine how it will react with other substances or change from one substance to another. The better we know the nature of the substance the better we are able to understand it.
