WebAug 30, 2024 · The commonly used long form of the periodic table is designed to emphasize electron configurations. Since it is the outermost (valence) electrons which are primarily involved in chemical interactions between atoms, the last electron added to an atom in the building-up process is of far more interest to a chemist than the first. WebValence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, ... This octet rule holds for elements in the second and third periods (or rows) of the periodic table.

WebDec 15, 2024 · When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds. WebJan 25, 2024 · Valence Electrons and Periodic Table The position of an atom in the periodic table represents the number of valence electrons present in the outermost shell of the atom. Across each row or period of the periodic table, the number of outer-shell electrons in groups \ (1 – 2\) and \ (13 – 18\) increases by one from one element to the next.
