Verified step by step guidance1
Understand that the atomic symbol is a one- or two-letter abbreviation derived from the element's name, often based on its English or Latin name.
Recall that 'Ag' is the atomic symbol for silver, derived from its Latin name 'Argentum'.
Recognize that 'Ga' stands for gallium, and 'Gd' stands for gadolinium, both different elements from gold.
Know that the atomic symbol for gold is 'Au', which comes from its Latin name 'Aurum'.
Therefore, identify 'Au' as the correct atomic symbol for gold based on its Latin origin.
