The electronic configuration of silicon atom (14Si) = 1s2, 2s2, 2p6 3s2 3p2 or [Ne]3s2, 3p2. A cation always has fewer electrons and the same number of protons as the parent atom; thus, it is smaller than the atom from which it is derived ().For example, the radius of a neutral aluminum atom (1s 2 2s 2 2p 6 3s 2 3p 1) is 118 pm, whereas the ionic radius of an Al 3+ (1s 2 2s 2 2p 6) is 68 pm. Since 1s can only hold two electrons the next 2 electrons for Silicon go in the 2s orbital. 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. And we can see that the potassium ion, K +, has the same electronic configuration as the chloride ion, Cl-, and the same electronic configuration as an atom of argon, Ar. If it is a silicon atom in an excited state, then you aren't talking about a cation or an anion (or it would be referred to as an "ion"). The electron configuration for Ca 2+ is the same as that for Argon, which has 18 electrons. It contains 14 protons and 14 electrons, with its most abundant isotope containing 14 neutrons. silicon.
