Which of the noble gases has only radioactive isotopes? Isotopes An element may have more than one isotope, which are atoms with the same number of protons and electrons. They have different numbers of neutrons. For example there are three isotopes of hydrogen, H-1, H-2, and H-3 having...

Ionic effects are larger in CsF than in LiF only in relative (relative to covalent effects), but not in absolute sense (see Table 1). This leads to ionic stabilization being not an absolute additive term, but a multiplicative enhancement factor, and the simplest formula is $${{D}}_{{\...
Show outer-shell electrons only. 4. Why did Kossel and Lewis’ octet rule lead chemists to believe that the noble gasese were totally inert? 5. Use the electron pair repulsion theory to predict the shapes of the molecules XeF 2 and XeF 4 . 6. Suggest reasons why all the known stable ...

Answer to: Atoms with more than two electrons achieve a noble gas structure by sharing enough electrons to attain an octet. Define the octet rule...
The borders of the periodic table of the elements and of the chart of nuclides are not set in stone. The desire to explore the properties of atoms and their nuclei in a regime of very large numbers of electrons, protons and neutrons has motivated new exp
We note that unlike other lanthanides, only La and Lu form non-magnetic ionic states like Y. Nevertheless, it is more natural to treat Lu as the first element in the d-block rather than treating it among the “rare earths”, since the 4f orbitals are filled up with 14 electrons as ...
