“At the core of the periodic system, what you have is chemistry,” Restrepo says ... first elements with electrons in the 8p orbital. This table is, of course, largely hypothetical.

It can be represented by ϕ. If we talk about the square of the orbital wave function, then it represents the probability of finding an electron. This wave function also helps us to draw the ...

Since then, the periodic table has evolved to reflect over 150 years of scientific development and understanding in chemistry and physics. Today, with 118 known elements, it is widely regarded as one ...

that would enable us to switch between the ‘regular’ and ‘converted’ orbital configurations. Using quantum chemistry and gas-phase thermochemical measurements, we expand significantly the ...
