The number of valence electrons in a magnesium (Mg) atom is 2.
Mg has an atomic number of 12, which means it has 12 electrons in total. The electron configuration of magnesium is 1s² 2s² 2p⁶ 3s². The electrons in the outermost energy level (the third energy level, in this case) are the valence electrons, and in the case of magnesium, there are 2 of them in the 3s² orbital. So, the correct answer is C. 2.
