A
Gold is a mixture of several metals.
B
Gold is an isotope of silver.
C
Gold is a compound made of gold and oxygen.
D
Gold is an element with the chemical symbol Au.
Verified step by step guidance1
Understand the nature of gold by recalling its classification in chemistry: gold is a pure substance, not a mixture or compound.
Recall that an element is a substance made of only one type of atom, and gold fits this definition as it consists solely of gold atoms.
Recognize that gold is not an isotope of silver; isotopes are variants of the same element with different numbers of neutrons, and gold and silver are different elements entirely.
Know that gold is not a compound; compounds are substances formed from two or more different elements chemically bonded together, which is not the case for gold.
Identify the correct statement: gold is an element with the chemical symbol Au, which is its unique identifier on the periodic table.
