q2 what is the difference between a transition metal and an f element? the transition elements are in the d-block, and in the d-orbital have valence electrons. they can form several states of oxidation and contain different ions. inner transition elements are in the f-block, and in the ...
Transition element definition: any element in any of the series of elements with atomic numbers 21–29, 39–47, 57–79, and 89–107, that in a given inner orbital has less than a full quota of electrons.. See examples of TRANSITION ELEMENT used in a sent

(Fig. 2-2) exists for every element. In the case of hydrogen the electron in the ground state (n= 0) can make a transition to an excited state provided (1) the state is vacant, and (2) the electron gains enough energy. The energy needed is simply the difference in energy between ...
