      2:51:09 Sir acc to Chat GPT : The 2z+1 and 2z trick is used in the calculation of atomic mass, not relative atomic mass. And atomic mass is easier than relative atomic mass.
      Sir , acc to Chat GPT : u used the relative atomic mass theory in atomic mass and atomic mass theory in relative atomic mass 😮
      Anyone pls help me with this confusion 😢🙏

    Sir if we take chlorine atomic mass which is 35.5 then it means what does it means it has half of something proton or neutron because it has .5

    • @g1gamerz2008
      @g1gamerz2008 หลายเดือนก่อน +1

      Atomic mass is equal to the mass of proton+neutron. If you have give any one of them, then you can calculate the other.
      Yes, may be, numerical value of any of them in decimal. But you can't tell the numerical value of which one is in decimal until the mass of either proton Or neutron is given.
      Reply again if my answer is correct and i am able to satisfy you with this answer. 😊

    2:51:10 Sir acc to Chat GPT : The 2z+1 and 2z trick is used in the calculation of atomic mass, not relative atomic mass. And atomic mass is easier than relative atomic mass.
    Sir , acc to Chat GPT : u used the relative atomic mass theory in atomic mass and atomic mass theory in relative atomic mass 😮
    Anyone who knowns the right concept pls help me with this confusion 😢🙏
