Physical atomism refers to the structural parts, forces, and properties of an atom. Chemical atomism refers to “the manner in which different elements relate and the new substances they form by their union.” - Abigail

Where, if any, was the work of Dalton proven to be incorrect?His second idea that all atoms of an element have the same weight was later proven to be incorrect when isotopes were discovered

Question 2: Where, if any, was the work of Dalton proven to be incorrect?

They are: “(1) chemical elements are made of atoms; (2) the atoms of an element are identical in their masses; (3) atoms of different elements have different masses; and (4) atoms only combine in small, whole number ratios such as 1:1, 1:2, 2:3 and so on.” Question 5 : What are the four basic ideas of Dalton’s chemical atomic theory?

# data[].attributes.body
In his experiments, he wanted to prove his hypothesis that “the sizes of particles making up different gases must be different.” Further, he ultimately wanted to determine the sizes, weights, and numbers of all chemical particles involved in any kind of chemical combination (reaction).

Question 1: What did Dalton ultimately wish to determine or prove?

It is believed that he arrived at his theory through his studies and experiments in meteorology, specifically in the areas involving vapor pressure, gas solubility, and gas mixtures.

Question 3: How did Dalton come to develop his chemical atomic theory?

# data[].attributes.body
Physical atomism refers to the structural parts, forces, and properties of an atom. Chemical atomism refers to “the manner in which different elements relate and the new substances they form by their union.” Students need to note that Dalton’s work dealt with chemical atomism and that advances in physical atomism came well after his death.
Question 4 : What is the difference between physical and chemical atomism?
