Understand that chemical symbols are one- or two-letter abbreviations derived from the element's English or Latin name.
Recall that magnesium is an alkaline earth metal with atomic number 12, and its symbol is derived from its English name.
Recognize that 'Mg' is the correct symbol for magnesium, where 'M' is capitalized and 'g' is lowercase, following the convention for element symbols.
Note that 'Mo' stands for molybdenum, 'Mn' stands for manganese, and 'Md' stands for mendelevium, which are different elements.
Therefore, identify 'Mg' as the correct chemical symbol for magnesium.
