In this question, daldin's atomic theory was proposed in 1808.
00:16
At that time, the concept of the atom was very different.
00:21
So, from what we know today, daldin believed that atoms were indivisible and indestructible.
00:28
So, daldin's he derived atoms were indivisible, indivisible and indestructible, indestructible.
00:45
So, he also believed atoms of the same element were identical in all the respects including mass, size and chemical properties.
00:55
So, including we can say like this, all atoms, all atoms of the same element were identical, were identical.
01:15
So, in all respects which is nothing but mass, size and chemical properties.
01:20
So, this was based on the observation that elements combine in fixed ratio.
01:26
So, the elements combines in the fixed ratio, elements combine in fixed ratio to form a compounds, fixed ratio to form compounds.

For example, we can take water, so let me down the page.
01:51
So, water is always composed of 2 hydrogen, 2 moles of h2 and 2, 1 oxygen atom.
01:59
So, 1 oxygen atom we can write like this 1 o2, so it gives the water molecule h2o...
