It has the properties of a noble gas because its outer electron shell is full, which makes it a stable element. It is colorless, odorless and unreactive just like many of the other noble gases.

Because it has 2 electrons in its K shell. Also, its electron configuration is 1s2. These statements mean that He has a filled shell and cannot become more stable by donating an electron or accepting an electron to form a filled shell.
