Are atoms indivisible?
No. Atoms consis of protons, electrons and neutrons which consist of quarks and whole bunch of subatomic particles.
ANSWER: The Greek word for indivisible is atom. It is rich with irony and even somewhat predictable that by naming something that small indivisible, it was only a matter of time before someone rose to the challenge.
Yes, but they lose the 'identity' of the element when they are divided. Atoms were once thought to be indivisible units of an element - the smallest thing that retained the characteristics of an element. The word comes from the Greek for indivisible/uncuttable ~ a + temnein. It is now known that atoms contain protons, neutrons and electrons and that even these are composed of smaller particles called quarks.
