Answer
Explanation:
Step1: Locate Mg in periodic table
Magnesium (Mg) has atomic number 12.
Step2: Determine electron - configuration
The electron - configuration of Mg is 1s²2s²2p⁶3s².
Step3: Identify valence electrons
Valence electrons are in the outermost shell. For Mg, the outermost shell is the 3rd shell with 2 electrons.
