Who said atoms are not indivisible?
Who was the English scientist that said all matter is made up of a relatively small number indivisible particles called atom?
He said that atoms were indivisible, and we now know is not true because atoms are composed of protons, electrons, and neutrons, and that protons and neutrons are themselves composed of smaller particles. He also said that all of the atoms of the same element have the same mass, which we now know is not true because of the existence of isotopes.
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.
Atoms can be divided, as in nuclear fission . . . but you said atom particles. Some of these little dudes can be split into other, high-energy particles. that's right but that doesn't answer the question!!!!! the answer is yes atom particles are invisible!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! It is right . . . read the question again. It says INDIVISIBLE, not invisable!
Democritus; together with Leucippus; are the first ones who mentioned that any element is composed of atoms. Their speculation on atoms, taken from Leucippus, bears a passing and partial resemblance to the nineteenth-century understanding of atomic structure The theory of Democritus and Leucippus held that everything is composed of "atoms", which are physically, but not geometrically, indivisible; that between atoms, there lies empty space; that atoms are indestructible; have always been, and always will be…
Democritus was the Greek philosopher who made a mental model of the atom. He said that atoms composed everything and were physically but not geometrically indivisible. Between the atoms there is empty space. They always will have been, and will be in motion and are indestructible. Different atoms differ in size and shape.
one of the postulates that is not considered true today is that atoms are indivisible^-^ He said that all atoms of a given element are alike. This is not true due to the existence of isotopes. Isotopes are atoms of the same element that have different masses because they have different numbers of neutrons. During a chemical reaction, atoms can change their identities
Postulates of Dalton's Atomic Theory: Atoms are made up of small indivisible particles called atoms. Atoms can neither be created, nor be destroyed. Atoms of same elements are similar in all respects, and atoms of different elements are different in all respects. Atoms combine together in simple whole number ratios, forming molecules. Of all these postulates, only the last one is correct.
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.
