In the periodic table of elements, silicon is represented by the chemical symbol Si, atomic number 14 and relative atomic mass of 28.085. The outermost electron, 6s 1, therefore, is held very loosely. While there are more protons in a cesium atom, there are also many more electrons shielding the outer electron from the nucleus. After the loss of first electron the electronic configuration of Na + is 1s 2, 2s 2 2p 6, i.e., that of noble gas which is very stable and hence the removal of 2 nd electron from Na + is very difficult. Therefore, you should write the electron configuration for 18 electrons. 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. In assigning electrons to specific orbitals, the electrons must fill the main energy levels first before moving on to the next. Join Yahoo Answers and get 100 points today. An atom's electron configuration is a numeric representation of its electron orbitals. 2.1) The atomic number of Silicon atom is Z = 14.
