Webb. Elements with the same number of valence electrons are in the same group or column on the periodic table. 4. After reviewing the terms, have students label their periodic tables with the terms Group and Period. 5. To play the game, each player should use their dry erase marker to circle a series of elements on the bottom periodic table ... WebAug 14, 2024 · The first two electrons in lithium fill the 1 s orbital and have the same sets of four quantum numbers as the two electrons in helium. The remaining electron must occupy the orbital of next lowest energy, the 2 s orbital (Figure 8.3. 3 or 8.3. 4 ). Thus, the electron configuration and orbital diagram of lithium are: flower that looks like an angel
