Electronic configuration is also referred to as electron configuration. Given below is a table describing the electronic configuration of first 30 elements … Carbon (C) 2. All group 13 elements have ns 2 np 1 valence electron configurations, and all tend to lose their three valence electrons to form compounds in the +3 oxidation state. Germanium (Ge) 4. The elements of the halogen group are highly reactive, non-metallic elements. These are all transition metals and chromium, molybdenum and tungsten are refractory metals.. 1. : Atomic These d-orbitals do not screen the nucleus effectively because of their poor shape and hence the effective nuclear charge of Ga increases and the radius decreases. thermistors. But in group 13 elements first, as we move from B to Al electronegativity decreases as expected but then increases down the group. Fig 1: Group 5 electronic configuration. remarkable for its unusually low melting point (29.7, therefore generally exist as a liquid at room What is the atomic number of this element? 3. thermistors. This list of electron configurations of elements contains all the elements in increasing order of atomic number.. To save room, the configurations are in noble gas shorthand. Flerovium (Fl) of electrons per cell in each of the elements. This happens because the tendency of ns 2 electron pair to participate in a bond formation reduces with increasing atomic size. c.
