Van der Vaals's forces of attraction are responsible for holding together atoms of an element.
Mixture, because it is mixed with all sorts of chemicals, such as smog, and or pollen.Mixture is NOT a pure substance, because to be a pure substance, it can't be mixed with anything.
pure substance, propanone
If the pure substance is not an element, the smallest part is a molecule (which is made of atoms) for instance, pure water is made of water molecules, which are made of 2 hydrogen atoms and 1 oxygen atom If the pure substance is an element, the smallest part is an atom. (which is made of Protons, Neutrons, and Electrons) Pure hydrogen is made of atoms. A stable hydrogen atom has 1 proton, 1 neutron, and 1 electron. Protons and Neutrons can be broken down further into Quarks, Leptons, and Bosons. The Electron is a type of Lepton.
a pure substance is made up of only one type of atom. atoms can't be broken down (divided) definition of an atom: that which cannot be divided. there ya go! ur welcome :) -shamansh
A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.
The smallest unit of a pure substance that consists of two or more atoms held together by a chemical bond is a molecule.
An element and compound. Element- A group of atoms with identical proton numbers, Compound- 2 or more DIFFERENT elements chemically held together.
A general name for a pure substance containing different atoms chemically joined together is a compound. Compounds are formed when atoms of different elements bond together through chemical reactions to create a new substance with unique properties.
No, ammonia is a compound composed of nitrogen and hydrogen atoms. It is not a pure substance as it is made up of different elements chemically bonded together.
F2 (fluorine) is an element and thus a pure substance. However a compound is a pure substance as well.
O2 is in fact a very pure substance. O2 is a pure substance because it's only atoms are oxygen atoms.
yes, oxygen is an example of a pure substance.a pure substance is made up of one kind of matter and it cannot be broken down into smaller parts.
It tells you the elements and the proportions of those elements that are present to make the pure substance.
Silicone is a pure substance made up of silicon, oxygen, carbon, and hydrogen atoms. It is not a mixture because these atoms are combined in a specific and consistent ratio.
Yes. Any substance is still pure so long as it only contains one type of atom. In fact oxygen, in its normal state, consists of two atoms bound together.
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
a element is a pure substance
