Using spdf noble gas notation, write the electron configuration for each of the following atoms. 1s 1s 25 2p 35 3p 45 3d 4p 5s 4d 5p 6s 5d 6p 7s 6d 7p 4f 5f - |s-block elements |d-block elements (transition metals) ]p-block elements |F-block elements: lanthanides (4f) and actinides (5f) (Express your answer using the noble gas notation. For example, the electron configuration of Li would be entered as [He]2s!.) a P

Two sets of ionizations are shown in the tables below. Complete the tables by ordering each set of ionizations by increasing amount of energy required. In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require the next least energy, and so on. energy energy required ionization ionization required Fr Fr + e Kr Kr + e S - S + e ?

CARD 1 #Fullfilled energy level atomic number orbital/sublevel family period f-block s-block p-block d-block electrons is one of the bases of how are the with Increasing elements in the Periodic Table are arranged. Elements similar properties are grouped as, 2 where the elements have the same number of electrons in their outermost shell and 1 3, where the elements have the same number of main energy levels. The periodic table of elements consists of 4 columns (Group 1A and Group 2A); the (Groups 3A to 8A); the, 2B); and the lanthanides and actinides.
