part g

Explanation:

Step1: Determine Na's electron configuration

Sodium (Na) has an atomic number of 11, so its electron configuration is $1s^2 2s^2 2p^6 3s^1$.

Step2: Analyze unpaired electrons

In the $3s$ orbital, there is 1 electron, and since an s - orbital can hold a maximum of 2 electrons (paired), a single electron in an s - orbital is unpaired. So, there is 1 unpaired electron.
