On the basis of electronic configuration, the elements may be divided into four groups, that is s, p, d & f. This division is based on the name of orbital which receives the valence electron. The electronic configuration of any orbital can be represented as: nl x. n is the number of principal shell, l = symbol of the sub shell or orbital, x= number of electrons present in the orbital. So, we sum up the external configuration of first-line transition elements as 4s 2 3d n. In any case, we already know that chromium and copper don’t follow this example. The number of subshells in a shell is equal to the value of its principal quantum number and each subshell is designated a value which is called the Azimuthal Quantum number, ‘l’. It may be noted that the electronic configurations of zinc, cadmium and mercury can be … Every shell is designated a value which is basically the Principal Quantum number, ‘n’. Cl has 7 valence electrons (3s2p5) and Co has 9 valence electrons (3d74s2)].Valence electrons are involved in chemical bonds - section 4.

So, for the 1, The number of subshells in a shell is equal to the value of its principal quantum number and each subshell is designated a value which is called the Azimuthal Quantum number, ‘l’. Electron configurations of elements beyond hassium (element 108), including those of the undiscovered elements beyond oganesson (element 118), are predicted. This is a result of very low energy distinction between the 3d shell and 4s shell. For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell. For each electron shell atom diagram, the element symbol is listed in the nucleus. Join now.
