    These videos are gems . No matter how old these videos are, their value will remain priceless. And people don't complaint or correct mam in video section because these videos are just like of leak videos. So they don't care about your correction because no one going to reply you.

      didn't find in the ncert . but in one of the source definitely magnesium was shown lesser than the potassium.
      But on the World economic forum website potassium is shown correct at the lowest but sodium was shown more than magnesium .
      I think its better we stop wasting time on these kind of useless fact bcoz they will never gonna ask such question bcoz no one actually know which is present in the least. As there are some other elements as well those are much lesser than these .

    CORRECTION At 2:53, I think Laplace nebula theory says to observe earth, as it has lighter elements on surface and ma'am gives example to simulate the angular motion of particle of sand in bucket and observe their behaviour.
    BUT, I think sand particle would be THROWN OUT due to centrifugal force.
    They would not be concentrated at the centre of rotational axis.
    This observation of earth being lighter outside gives support to Laplace claims that at some point all 9 pieces were revolving around ....
    Edit: revolving in H.He cloud.

    Laplace theory of havy elements moved towards centre and lighter elements towards surface is contradictory with the formation of planets ....if this is right then during the fastly rotating period of nebula sun should have havy elements and the other planets should have lighter elements......ex sun have H2 and Helium but other planets have C,O2,Fe, etc
