The '3' informs us that the element is in the 3rd Energy Level or row of the periodic table. Write an electron configuration for element X that shows the atom in a different excited state. Thus, for the first two elements, we would write their electron configurations as: H: 1s 1 and He: 1s 2. They are (1) size (radius) of atoms and ions, (2) ionization energies, and (3) electron affinities. Two are taken from the 4s sub-shell, the other from the 3d sub-shell. So basically then the transition metals are any element whose final electron enters the d sub shell and then for an inner transition metal with f orbitals, they. 1, 2 and 3 so the valence energy level or Shell is three. How many electrons are in the 4d orbitals of Tc? 19. You will see why in chem. When the atom is in excited state, one or more electrons go to a higher energy state, so electron configuration of the excited atom is different. The first electron has the same four quantum numbers as the hydrogen atom electron (n = 1, l = 0, m l = 0, ). Helium is unique since its valence shell consists of a single s-orbital. Following the principle you obtain the electron configuration of an atom by successively filling subshells in the following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f Use the following mnemonic diagram to help you remember the order.
