GENERAL KNOWLEDGE

Detailed explanation-1: -Gold, for example, is element number 79. 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. Therefore, gold is considered an element.

Detailed explanation-2: -A pure substance is matter that is uniform throughout and has consistent properties. All matter is made up of very small particles called atoms. Atoms are the building blocks of all matter. When a substance contains only one type of atom, it is called an element.

Detailed explanation-3: -A gold bar is made of just one thing: the element gold. Bronze is a homogeneous mixture of copper and tin. It’s a mixture (not a compound) because the proportions of copper and tin aren’t exactly the same in all bronze. Mixtures of metals are called alloys.

Detailed explanation-4: -Yes, gold is a pure substance. What is this? A substance is pure when there is no other type of element or compound in it. Gold is composed of only Aurum (Au) and nothing else.
