Gold is a shiny solid that conducts electricity.
A student says, "A single gold atom is also shiny and conducts electricity."

The student is incorrect, because these properties depend on very many gold atoms being bonded together.
The student is incorrect, because a single gold atom has no electrons in its outer shell.
