Helium is part of a group called the Noble Gases. This group is made up of six different gases, their names are: Helium (H), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
Helium is under group 18 and period 1. This makes helium a noble gas with the most electrons it can possibly have under stable conditions.
Neon, Argon, Krypton, Xenon and Radon.
Helium doesnot have a gender. It is a chemical element
gaseous state
Helium has 2 valence electrons.
Helium is a gas at STP
carbon (group 14, period 2) hydrogen (group 1, period 1) nitrogen (group 15, period 2) oxygen (group 16, period 2) sulphur (group 16, period 3) halogens (group 17, period 2-5)
heliums period address is 11.09
The Heliums period is a explosive force of matter which produces nano bits of helium. The shockwave contributes to events here on Earth. Scientists are still trying to decode the main details.
It is not an exception: it is at the top of group 18, the noble gases which is exactly where it should be.
