Find the number of electrons in chromium (overset24Cr) which have orbital angular momentum equal to `h//sqrt2pi`.

The orbital angular momentum of a 2p-electron is

The oribital angular momentum of an electron is 2s orbital is

According to Bohr's atomic model the electrons move around the nucleus in a circular orbit the electrons can move only in that orbit in which a angular momentum of electrons I sintegral multiple of h/2pi i.e. mvr=nh/2 pi where n=principle quantum number r=radius of orbit v=velocity of electron h=plank's constant the energy of orbit in which electron is moving is given by E_n=-13.6(z^2/n^2)eV//"atom" The radius of which of the following orbits is the same as that of the first Bohr's orbit of hydrogen atom?

Calculate the velocity of an electron in the first Bohr obit. Also calculate the de Broglie wavelength (in 'm') of the electron. Find the orbital angular momentum (in (h)/(2pi) units) of 3p orbital of hydrogen atom.

Statement I : The magnetic moment of an electron rotating in an atom is proportional to its angular momentum . Statement II : The electrons in an atom can rotate only if those orbits for which the angular momentum of the electron is an integral multiple of (h)/(2pi) (h - Planck 's constant ).
