Identify the atom or ion corresponding to each of the following descriptions: (a) an atom with ground-state electron configuration [Kr]4d105s25p1 (b) an ion with charge 22 and ground-state electron configuration [Ne]3s23p6 (c) an ion with charge +4 and ground-state electron configuration [Ar]3d3. 0000002954 00000 n Transcribed image text: a) 12. Write the expected electron configurations for each of the following atoms: Cl, Sb, Sr, W, Pb, Cf.
