Question

Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that _____. A) all of Dalton's hypotheses are correct. B) atoms of an element can have different numbers of protons. C) atoms are divisible. D) all atoms of an element are not identical but they must all have the same mass

Answer 1

It is now known that ATOMS ARE DIVISIBLE.
Contrary to Dalton hypothesis that says that atoms are indivisible, it has now been discovered that atoms are actually divisible. Each atom of an element is made up of three sub atomic particles, which are protons, neutrons and electrons. The protons and the neutrons are located in the nucleus of the atom while the electrons orbit round the nucleus. The proton is positively charged, the electron is negatively charged and the neutron has no charge. <span />

Answer 2

Atoms are now known to be divisible, in contrast to the early beliefs made by Dalton that the atoms are indivisible.  

Further Explanation:

The smallest matter of the element which retains the traits of that element is known as an atom. John Dalton was an English physicist, chemist, and meteorologist. He was widely known for his atomic theory. Dalton's atomic theory proposed that all matter was made up of atoms which can neither be divided further nor be destroyed further. Whereas all the atoms of an element were identical and different elements had the atoms of different mass and size.  

However, later it was proved that atoms are divisible. When an atom loses its known identity, it means that they are now divisible. Atoms basically react with other kinds of atoms, thereby, altering their activity. During a chemical reaction, there is an exchange of electrons. When electrons have moved that marks as the first evidence that an atom is divided. The second evidence is that the nuclear reaction proves that atoms can be divided. During nuclear reactions, the atoms are fused or segregated through a process called fusion or fission, respectively, in order to form another kind of element.
