Question

State the main points of dalton's atomic theory by modwrn atomic theory

Answer 1

Answer:Dalton's ideas were:

1)matter is made up of small particles called atoms;

2)atoms cannot be destroyed or created;

3)atoms of a particular element are all exactly alike and are different from atoms of another element;

4)when elements combine, whole numbers of atoms combine.

Explanation:

Answer 2

Answer:

The main presuppositions of Dalton’s infinitesimal proposition are

• The matter is made up of inseparable patches known as atoms.
• The parcels of all the atoms of a given element are the same including mass. This can also be stated as all the atoms of an element have identical mass while the atoms of different rudiments have different millions.
• Atoms of different rudiments combine at fixed rates to form composites.
• Atoms are neither created nor destroyed. This implies that during chemical responses, no atoms are created nor destroyed.
• The conformation of new products( composites) results from the rearrangement of atoms( reactants).
• Atoms of an element are identical in mass, size and numerous other chemical or physical parcels, but atoms of two-different rudiments differ in mass, size, and numerous other chemical or physical parcels.

The modern infinitesimal proposition contradicts dalton’s infinitesimal proposition:

• atoms are separable into protons, neutrons, electrons.
• atoms of the same element have different parcels, similar atoms are isotopes.
• atoms of different rudiments have the same parcels, similar atoms are isobars.
• atoms can combine at any rate and not just whole figures
