Answer» here is your answer mateExplanation:The THIRD SHELL is M shell .If the atom of the element has three electons in the third this means that K and L shells are already filled (a) Electronic CONFIGURATION : 2,3,8 , (b) Atomic number =No of electrons =13 (c ) Number of protons =No of electrons -=13 , (d) Valency of the element =3 (E ) The element with Z=13 is aluminium (Al) , (f) It is a METAL
