We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Arsenic should have five dots on its electron dot structure because it has five electrons in its outermost shell. They are important to an atom because the fewer valence electrons that the atom holds, the less stable it becomes. WebThe maximum number of electrons which will occupy the energy state in an atom is found by using the subsequent formula: Electron capacity = \(2n^{2}\) Magic Numbers.

E.g Fluorine (F) has 7 electrons in the outermost shell, and its valency could be 7 but it is easier for fluorine to gain one electron instead of losing seven electrons. The presence of eight electrons in the valence shell of an atom imparts stability to that particular atom. The existence of the electron showed that the 2,000-year-old conception of the atom as a homogeneous particle was wrong Their work culminated in the discovery by English physicist J.J.
