Just like water, salt can be separated using electrolysis too. Salt has a chemical formula of NaCl, which means it consists of Na atom (sodium) and Cl atom (chlorine). Salt, which is another famous example of a compound.But you can chemically do it using a process called water electrolysis. The molecule of water is always the same no matter where you find it. Water has a chemical formula of H2O, which means it consists of 2 Hydrogen atoms and 1 Oxygen atom. Water, it’s probably the most famous example of a compound.A compound always has the same composition, no matter where you find it. It means that you cannot physically break down a compound into something simpler.
You have learned what an element is, now you might be wondering, what is a compound?Ī compound is something that is happened when two or more elements are combined AND bonded chemically to each other. Oh, and because an element is pure, it cannot be broken down.
It may consist of A HUGE NUMBER of atoms (atoms are super tiny), but those are all one single type of atom. So, an element is basically a substance that is PURE without any addition. Graphite (also with the chemical formula of C) is an element because it only consists of atom Carbon.Diamond (with the chemical formula of C) is scientifically an element because it only consists of atom Carbon.Oxygen (with the chemical formula of O2) is an element because it only consists of atom Oxygen.When a matter consists of only 1 type of atom, the matter is considered an ELEMENT. By that, the matter can fall into one category: either element, compound, or mixture. There are various atoms in this world with unique characteristics.Ī matter can consist of 1, 2, or many types of atoms. You might have heard something about the atom, right?Įvery matter of this world consists of the atom(s). So, keep reading and learn more about the topic! What Is An Element? Now that you realized that there are two types of gold and to which classification they belong, you might want to know the reason behind it. However, gold jewelry is a mixture because it consists of various elements that vary in ratio. Pure gold is an element because it only consists of 1 type of atom, Aurum (Au). Is gold an element, compound, or mixture? Now you might be wondering, to which category does gold belong? In science, you can classify matters according to the physical property of it. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc.Gold is a beautiful matter that you can find in jewelry. Chemical properties are only observable during a chemical reaction. The better we know the nature of the substance the better we are able to understand it. What are the Chemical Properties of Gold? They are the characteristics that determine how it will react with other substances or change from one substance to another. Gold Properties - What are the Chemical Properties of Gold? It can be beaten into extremely thin sheets of gold leafĪ relatively soft metal, gold is usually hardened by alloying with copper, silver, or other metals. What are the Physical Properties of Gold?
