Document Summary
In short, electron and proton, oppositely charged particles that should attract according to (cid:272)lassi(cid:272)al ph(cid:455)si(cid:272)s, do(cid:374)(cid:859)t (cid:272)ollapse o(cid:374) o(cid:374)e a(cid:374)othe(cid:396) si(cid:374)(cid:272)e the(cid:396)e(cid:859)s (cid:374)o e(cid:374)e(cid:396)g(cid:455) state/orbit associated with electrons being on nucleus. Boh(cid:396)(cid:859)s (cid:373)odel, which first introduced the idea of electron orbits with specific energy levels, perfected by the probability density function psi^2 explain why e- and p+ of nucleus stay apart in an atom. Psi^2 is a function that describes the probability of finding e- within particular v; it is used to create radial probability distribution plot, which shows the total probability of finding the e- at some r from the nucleus. To construct the plot, the volume around nucleus is imaginary divided into spherical layers. And near the nucleus, the volume of the layers increases faster than the probability (cid:894)(cid:862)de(cid:374)sit(cid:455) of dots(cid:863)) of finding an e- there. Such opposing relationship gives: the probability of finding e- peaks in a layer near, but not at (cid:374)u(cid:272)leus.
