8-Write the orbital diagram that represents the ground state of Zn

9-Write the ground state electron configuration for Mg^2

10- Write the reaction below that represents the electron affinity of Li in the space provided.

Explanation / Answer

The atomic number of chlorine is 17. Its electronic configuration is 1s2 2s22p63s23p5. From the electronic configuration we can see that is has an unpaired electron in a 3p sub-shell. So, the quantum numbers would be n = 3; l = 1; m = + 1; s = +/-
