The electron in Bohr's model of hydrogen atom is pictured as revolving around the nucleus in order for it to

(A) bohr model can not be extended to two or more electron atoms. (R) each electron in the atom interacts not only with the positively charged nueleus but also with all other electrons.

In Bohr model of hydrogen atom, the force on the electron depends on the principal quantum number (n) as

Using Rutherford's model of the atom, derive the expression for the total energy of the electron in hydrogen atom. What is the significance of total negative energy possessed by the electron?

An atom that loses electrons becomes a positively-charged ion called

In the Thomson's model of atom, which of the following statement are correct ? (i) The mass of the atom is assumed to be uniformaly distributed over the atom. (ii) The positive charge is assumed to be uniformaly distributed over the atom. (iii) The electrons are uniformaly distributed in the positively charged sphere. (iv) The electrons attract each other to stabilise tha atom.
