Practice B.Sc Chemistry Structure of Atom in the app →The maximum number of electrons that can be accommodated in the $n$-th shell of an atom is:The four quantum numbers describing an electron in an atom are:
Hund's rule of maximum multiplicity states thatAccording to Heisenberg's uncertainty principle, $\Delta x \cdot \Delta p \geq$:Two electrons in the same orbital must have:Calculate the de Broglie wavelength of an electron moving at $10^6$ m/s. (Take $h = 6.6 \times 10^{-34}$ J·s, Bohr's first postulate: electrons revolve in ___ orbits around the nucleus.In Bohr's model, angular momentum of an electron in orbit n equals:Energy of electron in n-th orbit of hydrogen:Principal quantum number n indicates:Number of orbitals in subshell of azimuthal quantum number l:How many electrons can fit in a single orbital?Electron configuration of carbon (Z = 6):For hydrogen, wavelength emitted in n=3 to n=2 transition (Balmer):
