What seems to be the general relationship between an atom's atomic number and it’s placement on the Periodic Table?
number of protons in the nucleus and number of electrons in the different shell
explained : determine the position in the periodic table. ... Their position is decided by their Atomic Number which is the number of protons in the nucleus of the atom.
the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.
as per the hunds rule:
1. electrons tend to avoid being in the same orbital as per as practicable.
2. electrons in different orbitals of the same energy will have their spin parallel.
this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
