Based on equation , certain conclusions are written. Which of them is not correct ?
View answer and explanation
Correct option: C
For , the electron has a more negative energy than it does for which mean that the electron is more loosely bound in the smallest allowed orbit.
Option C (For , the electron has a more negative energy than it does for which mean that the electron is more loosely bound in the smallest allowed orbit) is not correct because a more negative energy indicates a *stronger* binding to the nucleus, not a looser one.

Which of the following pairs have identical values of e/m?
The correct de Broglie relationship is:
Assertion: Unlike sound waves, electromagnetic waves do not require medium and can move in vacuum.
Reason: The oscillating electric and magnetic fields produced by oscillating charged particles are parallel to each other and both are perpendicular to the direction of propagation of the wave. S-I: The orbital has maximum electron density along the y axis and its nodal plane is xz plane.
S-II : For a given atom, for all values of , the -orbitals have the same shape, but the overall size decreases as '' increases. S-I: Elements like and were discovered when their minerals were analysed by spectroscopic methods.
S-II: The element helium was discovered in the sun by spectroscopic method. In which one of the following, the number of protons is greater than number of neutrons but number of protons is less than the number of electrons?
