Which elements on the periodic table are pure?
Well technically, they're all pure in their pure form. haha, The question doesn't really make sence. You should look up what an element means. An element is just a category that an atom may fall into. The question of purity can't be asked about an element. You can ask "is this sample of matter of the element (blank) pure?" But not about the element itself
Are all metals pure elements?
All metals are pure elements, however do not occur in nature necessarily as "pure." Pure being defined as the singular element without added compounds for its stability. For example, Fe2+ (iron) is commonly found in nature as FeO2 (iron oxide) because iron is oxidized in the presence of air (hence the oxygen). There are a variety of elements that all need some kind of an ion (charged particle) as a supplement for the elements' stability, commonly Lithium, Sodium, Calcium and others are in complex with the "pure" element. Another common example is table salt (NaCl). Sodium metal (Na) is highly reactive with water and humidity and is also often complexed with some other element to maintain stability.
non examples of an ion?
Pure elements. Isotopes. Atoms.
What is a pure substance that contains only one kind of particle?
I thought it was pure substance. But i recently took a Science Test of these subject(i'm also in 8th grade) and it was the same question...EXACTLY! I put down Pure substance as well but appearantly the answer was "All of the Above" which included A.Pure Substance B.Compound C.Element ... so as long as you can prove it was only pure substance( This was for extra credit to get points back on the test for my teacher) You got the points. In my opinion a Pure Substance is the substance in which there is only one type of particle. I hoped this helped :)
