A magnesium (Mg) atom is not actually twice as heavy as a carbon (C) atom; rather, it has a greater Atomic Mass due to its greater number of protons and neutrons. Magnesium has an atomic number of 12, meaning it has 12 protons, while carbon has an atomic number of 6, with 6 protons. The atomic mass of magnesium is approximately 24 u (atomic mass units), while carbon is about 12 u. Thus, magnesium is roughly twice as heavy as carbon, but this is due to its larger atomic structure and the presence of additional neutrons, not simply the number of protons.
