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

    The magnitude of energy, the magnitude of linear momentum and orbital radius of an electron in a hydrogen atom corresponding to the quantum number n are E, P and r respectively. Then according to Bohr's theory of hydrogen atom:

    STATEMENT-1 : The energy of an electron depends only upon principal quantum number in case of hydrogen and hydrogen like ions. and STATEMENT -2 : The energy of an electron depends on principal quantum number as well as azimuthal quantum number for other atoms.

    The magnitude of angular momentum, orbital radius and time period of revolution of an electron in a hydrogen atom corresponding to the quantum number n are L , r and T respectively. Which of the following statement (s) is/are correct?

    The cation energy of an electron is largely determined by its principal quantum number. The principal quantum number n is a measure of the most probable distance of finding atomic the electron around the nucleus.

    When a particle as an electron exist in a box, three quantum numbers are necessary to describe the spatial distributioni fo electrons in atoms. The describe an electron in an atom completely, a fourth quantum number, m_(s) called the spin quantum number must be specified. This is because every electron has magnetic moment associated with it which is quantized in one of two possible orientations. Electrons having the same spin strongly repel each other and tend to occupy different region of space. This result of a fundamental law of nature is known as Pauli exclusion principle. The orbital angular momentum of an electron in 2s orbital is
