Helium has an atomic number of two, so its outer energy level is full. Helium is considered inert. The correct option among all the options given in the question is the second option. It is actually non toxic in nature. Helium is also colorless, odorless and tasteless in nature. It is the first in the noble gas group of the periodic table.
