What did Dalton's atomic theory state and its modifications?

Answer 1

Here are all five listed in the Modern Chemistry text book. I've put the one that have been revised in bold. (numbers 3 and 5)

1. All mater is composed of extremely small particles called atoms.
2. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass and other properties.
3. Atoms cannot be subdivided, created, or destroyed.
4. Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
5. In chemical reactions, atoms are combined, separated, or rearranged.

This list is on page 68 of the Modern Chemistry (2011) textbook, and the explanation is at the bottom of page 69.

Answer 2

Dalton's atomic theory stated that all matter is made up of indivisible particles called atoms, which differ in properties based on their element. It also proposed that chemical reactions involve the rearrangement of atoms. Modifications to Dalton's theory include the discovery of subatomic particles (electrons, protons, neutrons), isotopes, and the ability of atoms to be split in nuclear reactions.

Answer 3

Oh, dude, like, Dalton's atomic theory was all about those tiny particles called atoms being the building blocks of matter, right? And then, over time, scientists were like, "Wait, there's more to it!" So they made some modifications, like realizing atoms can be broken down into even smaller particles, and that they're not all identical. Science, man, always evolving and stuff.

Answer 4

Well, Dalton's atomic theory stated that all matter is made up of tiny particles called atoms, which are indivisible and indestructible. Over time, scientists discovered that atoms can actually be divided into subatomic particles like protons, neutrons, and electrons. This modification helped us better understand the structure of atoms and how they interact to form molecules and compounds.

Answer 5

Well, honey, Dalton's atomic theory basically said that atoms are indivisible and that all atoms of a given element are identical. But let's be real, science has come a long way since then, and we've made some modifications. We now know atoms can be divided into subatomic particles and that not all atoms of the same element are identical due to isotopes. So, in a nutshell, Dalton was on the right track, but we've jazzed it up a bit since his time.

Answer 6

state three dalton's theory and their modification

Answer 7

Atoms are not the smallest particles, they are made up of protons, neutrons, and electrons. All atoms of an element are not identical, some have different numbers of neutrons called isotopes.

Answer 8

These assertions are not valid today:
· All atoms of a given element are identical. · A given compound always has the same relative numbers of types of atoms.
