How many beryllium valence electrons
WebBeryllium is the fourth element with a total of 4 electrons. In writing the electron configuration for beryllium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining 2 electrons for Be go in the 2s orbital. Therefore the Be electron configuration will be 1s 2 2s 2.
