Question

explain any three postulate of dalton's atmoic theory with example ​

Answer 1

$\mathfrak{\huge{\green{\underline{\underline{Answer :}}}}}$

The matter is made up of indivisible particles known as atoms.

The properties 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 elements have different masses.

Atoms of different elements combine in fixed ratios to form compounds.

Atoms are neither created nor destroyed. This implies that during chemical reactions, no atoms are created nor destroyed.

The formation of new products (compounds) results from the rearrangement of existing atoms (reactants).

Atoms of an element are identical in mass, size and many other chemical or physical properties, but atoms of two-different elements differ in mass, size, and many other chemical or physical properties.

Answer 2

Answer:

John Dalton, a British school teacher, published his theory about atoms in 1808. His findings were based on experiments and the laws of chemical combination.

The 5 postulates of Dalton's atomic theory are listed below.

1-All matter is made up of atoms, which are tiny, indivisible particles.

2-All the atoms of an element have the same size, mass, and properties but the atoms of different elements have different sizes and masses.

3-Atoms cannot be created, destroyed, or divided into smaller particles.

4-Compounds are formed when the atoms of different elements combine with each other in fixed, whole-number ratios.
