Answer:
Gold bars, gold nuggets, gold dust, coins, and jewelry are all made of the same type of atoms, and they cannot be broken down into anything simpler. The atoms in one piece of gold are identical to the atoms in any other.
Explanation:Within atoms, electrons are arranged in layers called "shells", and gold is particularly unreactive as its outermost shell is full of electrons, which is a particularly stable state for an atom. Unlike some atoms with full outermost shells, like helium and neon, gold can react with some other chemicals.
