Having a maximum of 8 valence electrons explains why, from the third shell onwards, the next shell begins to fill before the current shell is full. Instead of drawing the electron configuration of an atom each time, it can be written in an abbreviated form. This is simply the numbers of electrons in each...Each Lewis dot symbol consists of the chemical symbol for an element surrounded by dots that represent its valence electrons. Cesium, for example, has the electron configuration [Xe]6s1, which indicates one valence electron outside a closed shell. In the Lewis dot symbol, this single electron is represented as a single dot:
All of the elements in family 2A have the same outer energy level electron configuration and the same number of valence electrons (two). Each of these atoms is a metal with low first and second ionization energies. Therefore, these elements will lose both of its valence electrons to form an ion with a charge.
