Atom comes from the Greek word meaning indivisible. This was because it was thought that atoms were indivisible then. Now we know that atoms are not infact indivisible but are made up of electrons, neutrons and protons.
That's called.. a molecule.
The cycloalkane with 12 carbon atoms is called cyclododecane. It has a molecular formula of C12H24 and forms a stable ring structure containing 12 carbon atoms.
Protons are found in the nucleus of all atoms and are positively charged.
The forces that hold atoms and molecules together are called chemical bonds. These bonds are formed through the attraction between the positive and negative charges of atoms, leading to the formation of stable structures such as molecules and compounds.
Petrol is called a hydrocarbon because it is primarily composed of molecules containing hydrogen and carbon atoms. The main components of petrol are hydrocarbons such as octane, which is a chain of eight carbon atoms bonded together with hydrogen atoms.
