An electron has a spin quantum number +1/2 and a magnetic quantum number -1, It cannot be present in:

Which has higher energy 3d or 4s orbital why?

An electron has a speed of '600 m / s' with an accuracy of '0.005 % .' The certainty. with which the position of the electron can be located is

According to Bohr's atomic theory, angular momentum of an electron in the orbit is quantised. Which among the following cannot be the value of angular momentum in a Bohr orbit.

Given below are the sets of quantum number for given orbitals. Name the orbital. n=2, l=1, m_(1)= -1

Assertion: When the atoms of first transition series ionize, the 4s-orbital electrons are ionized before 3d-orbital electrons. Reason: The energy of 3d-orbital electron is lower than that of 4s-orbital electrons.
