WebAs you point out, krypton ( K r) and xenon ( X e) are members of the Noble gas family. They are generally unreactive (noble) because all of their occupied orbitals are filled with electrons - they really don't want to gain or lose an electron. However, in the 1960's researchers found that K r and X e did react with extremely electronegative ...
WebLet's start with the prior that in a hydrogen atom the principle quantum number determines the energy - so maybe full shells correspond to noble gases. Now, I understand that in helium the n=1 level is full, so it is a noble gas. Then, beryllium has a full 2s subshell, but empty 2p, so it is a metal. Neon has the n=2 level full, and is a noble gas. highlights january 6WebDec 14, 2010 · Do all of the noble gases have at least 3 electron shielding layers?
