Hydrogen is not a noble gas. Only the elements in the farthest right-hand column of the Periodic Table of Elements are noble gases. They are the gases whose outer energy levels are completely full. They cannot bond with other elements because of this. The electrons ( which starts out equivalent to the protons-- atomic number), circle the nucleus in energy levels. The first energy level can hold only two electrons. Any after that will hold up to eight. If the outer energy level ( valence) is full, it is called a noble gas and cannot bond with other elements. If the outer energy level is half full, they can share electrons with another atom; if the valence is more than half full, but not full, they gain electrons, and if it is less than half full, they lose electrons. The noble gases ( inert gases is another name for them) are: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). Hope this helps!
Not generally because noble gases are those that exist in as single atoms with a full octet and inert. The H2 molecule has a completed outer shell and is a gas but is very reactive. N2 is a stable non-reactive gas but not a single atom noble gas. All the Noble gases are single atoms with a full octet of electrons and at the far right of the periodic table.
Why isn't hydrogen a nobel gas....? Does it have a different level of electrons but it is in a gas like state?
The nobel gases are the first gases on the periodic table and the basic building blocks for all the other chemical elements of a given substance.
