What portion of daltons atomic theory is still considered correct?

Answer 1

Dalton believed that all elements were composed of tiny indivisible particles called atoms. We now know that this is not true, there are particles found within the atom: protons, neutrons, & electrons. Dalton believed that all atoms of the same element were identical. We know this is not true. Isotopes are atoms of the same elemtn that have different mass numbers because of different numbers of neutrons, therefore, all atoms of the same element are NOT identical

Answer 2

The portion of Dalton's atomic theory that is still considered correct today is the concept that elements are composed of indivisible particles called atoms. While Dalton's idea that atoms are indivisible has been proven incorrect with the discovery of subatomic particles, the fundamental idea that elements are made up of distinct, unique atoms remains a cornerstone of modern atomic theory. Additionally, Dalton's theory also proposed that atoms of the same element are identical in mass and properties, which is still accepted today with the understanding that isotopes can have variations in mass.

Answer 3

The concept that elements are made up of atoms and that atoms of the same element are identical in size, mass, and properties are still considered correct. Additionally, the idea that chemical reactions involve the rearrangement of atoms is still relevant.

Answer 4

No. The postulates of Dalton's Theories have been proved wrong by the modern scientists and there theories. Almost all his theories are wrong according to the modern scientists.

Answer 5

not everything.. some are true some are not

Answer 6

1. All matter is made of atoms.

2. Compounds are formed by the combination of two or more different atoms.

3. A chemical reaction is a rearrangement of atoms.
