Are particles bigger than molecules?
No, particles are little parts of atoms that chooses what type of atom it will be.Such as gold or iron.Particles are electons,nuetrons and protons.The amount of each proton nuetron or electron also chooses what type pf atom it will be.A molicule is several atoms put together
What was Mendeleev's contribution to the knowledge of elements?
When making his periodic table Mendeleev noticed some spaces where elements should be couldn't be filled. He didn't want to force elements that didn't belong there to go there, so he believed the spaces were undiscovered elements. He left the names blank but predicted their properties. Later the elements Mendeleev predicted existed were discovered.

Are all compounds molecules?
YES!!!!!!!! All compounds are molecules HOWEVER not all molecules are compoundsTechnically, no. Ionic compounds form a crystal lattice rather than individual molecules. A compound is any combination of at least two different elements.
What does chemically combined mean?
Chemically combined refers to the process of something being combined with something else via a chemical reaction. They cannot be physically split up, as they require another chemical reaction to separate them.
What happens when two elements combine chemically?
When element chemically combine, they form compounds that have properties that are similar to those of the uncombined elements
Molecules that contain atoms from several elements form a what?
Molecules that contain atoms from several elements for a compound. Examples of these compounds include hydrogen, sodium chloride, methane, and magnesium.
How are molecules atoms that carry no charge?
Molecules are not atoms, but are made up of several atoms. The individual atoms may carry a charge, but when combined, the molecule as a whole does not.
