The valence electrons are the electrons in the outermost shell. Download Chemistry Slime Tutorial (7-12) PDF for free. According to the VSEPR Theory the compound is shaped a tetrahedral because it has four electron pairs of chlorine. Lewis structures don't tell us everything, but along with molecule geometry and polarity they are hugely informative. The server you are on runs applications in a very specific way in most cases. san antonio housing authority login . A pair of atoms can also share four electrons or six electrons. A lone electron pair is represented as a pair of dots in a Lewis structure. Hence, (6 valence electrons as dots + one single bond that contains 2 electrons) = 8 valence electrons are present around each bromine atom, hence, they all completed their octet. 7. germanium bromide.
