A radioactive nucleus A finally transforms into stable nuceus B. then A and B can be
Magnetic moment due to the motion of the electron in nth energy state of hydrogen atom is proportional to:
the ratio between total accelration of the electron in singly ionized helium atom and hydrogen atom (both in ground state)
a y ray photon is emitted:
difference between nth and n+1th Bohr's radius of 'H' atom is equal to its n-1th Bohr's radius. The value of n
