Write the electron configurations for the following elements. Then write the number of valence electrons in the space provided. For each element:
- Make sure to separate the last subenergy level into its orbitals
- Fill in the ( ) with the atomic number (Z) which is also the number of protons (but also electrons, e- )
1. Beryllium (Z= )
# of valence e-
2. Aluminum (Z= )
# of valence e-
3. Sodium (Z= )
# of valence e-
4. Argon (Z= )
# of valence e-
5. Calcium (Z= )
