List of top Physics Questions on Atomic Structure asked in AP EAMCET

A mixture consists of two radioactive materials \( A_1 \) and \( A_2 \) with half-lives of 20 s and 10 s respectively. Initially, the mixture has 40 g of \( A_1 \) and 160 g of \( A_2 \). The amount of the two in the mixture will become equal after
The decrease in each day in the Uranium mass of the material in a Uranium reactor operating at a power of 12 MW is (Energy released in one \(^{92}U\) fission is about 200 MeV)
Energy levels A, B, and C of a certain atom correspond to increasing values of energy, i.e., \( E_A<E_B<E_C \). If \( \lambda_1, \lambda_2, \) and \( \lambda_3 \) are the wavelengths of a photon corresponding to the transitions shown, then:
Energy levels A, B, and C
If the bonding energy of the electron in a hydrogen atom is 13.6 eV, then the energy required to remove an electron from the first excited state of Li\(^{2+}\) is

A hydrogen atom falls from nth higher energy orbit to first energy orbit (n = 1). 

The energy released is equal to 12.75 eV. The nth orbit is

The principal quantum number \( n \) corresponding to the excited state of \( He^+ \) ion, if on transition to the ground state two photons in succession with wavelengths \( 1026 \text{\AA} \) and \( 304 \text{\AA} \) are emitted: \((R = 1.097 \times 10^7 \text{ m}^{-1})\)
