An ordinary molecule, strictly speaking, is not a single element, but a mix of elements... and thus a substance. Example: Water, good old H2O, is a molecule. It has 2 atoms of hydrogen, and one of oxygen, which have bonded together. If you have enough molecules you could have a drop of water, a mole of water, a gallon of water, an ocean of water. Of course water is the best solvent in our part of the universe - it is called the universal solvent - and it will dissolve various other substances in it. sugar, salt, and so on. But what if you had a lot of a single atom, an element like, say, gold? Well, that would not be a molecule. It would merely be a group of gold atoms than have bonded together. The bonding here, is more physical, than chemical (as it was in the H2O). You could then have an ounce, a mole, a ton of gold.... (Hey, I like that idea!) What of a gas, like hydrogen. Again, if you had a balloon full of hydrogen, it would be a bunch of pairs or atoms of H2. This is the sole case - the diatomic molecules - where atoms actually form molecules, but they are PURE elements. The entire list is: Cl O N F Br I H. And if you lit a match to that gas bag full of hydrogen? Ah, then you have the Hindenburg disaster. And that would be a terrible, unfortunate thing. (Which if you Google it, actually did happen.) But what if I had some oxygen, and I cooled all those O2 (diatomics) atoms down until they became liquid Oxygen - LOX? Well then I have 1/2 of the needed "fuel" for a rocket. But that LOX is VERY cold. and at the first opportunity, unless kept cold and compressed, it will sublimate, and vanish into thin air... most probaly freezing solid anything it came into contact with, like you. So if you see a pool of liquid Oxygen or Hydrogen, or what not, do NOT dive in for a swim. Also avoid any sparks, flames, or glowing splinters of wood. The boom would be a big one.

GOLD is a chemical ELEMENT with the symbol Au (from the Latin aurum) and atomic number 79.
A MOLECULE of Gold (this is the smallest amount while still retaining its properties - a single piece) has an atomic mass of 196.96 g*mol^-1
Pure Gold is too soft for practical use, however it is NOT A LIQUID in its natural state. It is usually mixed with other metals due to its maleable characteristics.

pure gold is an element. if heated to a high temperature, gold can become a liquid. one molecule of gold is symbolised by Au.

Gold is an element with the symbol Au and an atomic number of 79. It is the most malleable and ductile metal; 1 ounce (28 g) of gold can be beaten out to 300 square feet. It is a soft metal and is usually alloyed to give it more strength. It is a good conductor of heat and electricity, and is unaffected by air and most reagents.

first thing i tell you that pure gold is the perfect element which is made up of large no of small molecules , and it is in solid state...

element
its not a molecule becoz it is not diatomic(metals cannot be diatomic such as nonmetals)ex iodine is diatomic I2(2 is subscript)
its not a liquid becoz it is found in nature in a form of a solid
