Electrons revolve around the nucleus in definite orbits called .........

Electrons revolve around the nucleus in fixed orbits or shells called energy levels'. State how these energy levels are represented.

In an hydrogen atom, the electron revolves around the nucles in an orbit of radius 0.53 xx 10^(-10) m . Then the electrical potential produced by the nucleus at the position of the electron is

Electrons are revolving around the nucleus in n_(1^(th)) orbit of an atom, have atomic number Z_1 , and in the n_2 orbit of other atom, have atomic number Z_2 , then [Where P= Linear momentum, L=Angular momentum, f=frequency of revolution and K.E. =kinetic energy]

Derive an expression for the magnetic moment (vec mu) of an electron revolving around the nucleus in termsof its angular momentum (vecl) . What is the direction of the magnetic moment of the electron with respect to its angular momentum?

If an electron revolves around a nucleus in a circular orbit of radius R with frequency n, then the magnetic field produced at the center of the nucleus will be

When an electron revolves around the nucleus, then the ratio of magnetic moment to angular momentum is

(a) Obtain an expression for the equivalent capacitance when three capacitors are connected in parallel (b) An electron revolves around the nucleus of hydrogen atom in a circular orbit of radius 5 xx 10^(-11)m. Calculate : (i) intensity of electric field of the nucleus at the position of the electron. (ii) electrostatic potential energy of the hydrogen nucleus and electron system.

At what speed should the electron revolve around the nucleus of a hydrogen atom in order that it may not be pulled into the nucleus by electrostatic attraction ? Take the radius of orbit of an electron as 0.5Å , the mass of the electron as 9.1xx10^(-31) kg and charge as 1.6xx10^(-19)C .
