The calcium ion (Ca 2+), however, has two electrons less. The energy increases as we move up to the 2s and then 2p, … Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons.. An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy. Helium is unique since its valence shell consists of a single s-orbital. An electronic configuration is the way in which electrons. What Is the Electron Configuration of Calcium. This is well explained on the basis of sub shell electronic configuration. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of l differ so that the energy of the orbitals increases within a shell in the order s < p < d < f. Figure 1 depicts how these two trends in increasing energy relate. The electron configuration for Calcium is 2-8-8-2 (2 electrons in the first shell, 8 in the second shell, 8 in the third shell, and 2 in the fourth shell). The energy of atomic orbitals increases as the principal quantum number, n, increases. Schematic electronic configuration of calcium. 4s2 and the term symbol is 1S0. The subshells have a distinct shape and configuration, in which the electrons move freely. Since we need to take away two electrons, we first remove electrons from the outermost shell (n=4).
