    Somehow I feel lucky, to have found this video- I could actually visualise this :)
    Thank you so much sir for such an in-depth teaching. Literally nobody thought this topic in this manner!
    Keep making such videos sir..these are unimaginably helpful.

    The extra fraction in the relative atomic mass of an element, such as chlorine having a relative atomic mass of approximately 35.5 amu, is not due to electrons. The relative atomic mass primarily considers the mass of the protons and neutrons in the nucleus of the atom.
    The reason for the fraction comes from the presence of isotopes of the element. Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. Since isotopes of an element have different masses, their presence in nature affects the overall average atomic mass of the element.

    Best explained.But the atomic mass of C-12 is 19.92×10-24 g, determined by a specific weighing instrument. The question is that the atomic masses of other elements can also be determined by using this instrument.Why do we need the method of relative atomic mass if the atomic mass can be determined by such weighing instruments? Pls reply.

      another question is, to find out R.A.M we need the mass of given element. If i can measure the mass of total element, what's the need of relative atomic mass?

  • @ritwiksaha2325
    @ritwiksaha2325 3 ปีที่แล้ว +9

    The relative atomic masses of some elements are found to be fractional because they consist of a mixture of isotopes of that particular element and the resultant is the average of their relative atomic masses.For example the relative atomic mass of chlorine is 35.5 amu because it is the average of the relative atomic mass of Cl-35 and Cl-37 present in the ratio of 3:1 so that the relative atomic mass of Cl comes out to be (35×3+37×1)/4=35.5 amu

      One proton or neutron k value ko 12 se multiply kiya hain... kyun ki C12 mein 6 proton + 6 neutron presnt hota hain =12 particles present in the C12 nuclus... So, mass of 1protonor or neutron = 1.66×10^-24 g × 12 the total number of particles(6 proton and 6 neutron) present in the C12 nucleus is equal to to the total mass of C12 atom.
