Step 1:: Understand the Definition of an Element
An element is a pure substance composed of only one type of atom. In this case, gold (Au) is a pure substance made up exclusively of gold atoms. It cannot be broken down into simpler substances through chemical means.
Step 2:: Verify Gold's Atomic Composition
Gold ($$\mathrm{Au}$$) appears on the periodic table as a single element with the atomic number 79.
It consists of only gold atoms and cannot be separated into different types of atoms through chemical reactions.
Step 3:: Eliminate Other Options
- A mixture contains multiple different substances or elements physically combined - A compound is a substance formed by chemically combining different elements - Gold does not fit either of these definitions
Step 4:: Confirm Classification
Gold is a pure element because: - It is made of only gold atoms - It appears as a single entry on the periodic table - It cannot be chemically separated into simpler substances
Final Answer
Element The correct answer is A. Gold is a pure element consisting solely of gold atoms.
