WebJun 26, 2016 · The quick answer here is that because tin, Sn, is a main-group element, the number of valance electrons will be given by its group number. Tin is located in group 14 … WebThe element sodium has the electron configuration 1s 2 2s 2 2p 6 3s 1. The outer energy level is n = 3 and there is one valence electron. The attraction between this lone valence electron and the nucleus with 11 protons is shielded by the other 10 core electrons. The electron configuration for cesium is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 ...
WebAnswer: Inner, outer, and valence electrons are the different placements, or positions, an electron can have in the orbit ranges surrounding its atomic nucleus. Valence electrons are the farthest out and are often the ones associated in atomic bonding. Outer electrons are located slightly inward,... WebEvery subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals.
