Answer #1

The z-component of orbital angular momentum is given by: L_z = m_l \hbar

where m_l \epsilon {.....,-2,-1,0,1,2,......} is called magnetic quantum number.

Obviously from given options the possible values are 0, +\hbar, -\hbar

    Which of the following set of quantum numbers (ordered n,l,ml,ms) are possible for an electron in an atom? Quantum Number Rules Learning Goal: To learn the restrictions on each quantum number. Quantum numbers can be thought of as labels for an electron. Every electron in an atom has a unique set of four quantum numbers. The principal quantum number n corresponds to the shell in which the electron is located. Thus n can therefore be any integer. For example, an...

    Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (), the magnetic quantum number (m), and the spin quantum number (ms) have strict rules which govern the possible values. Identify allowable combinations of quantum numbers for an electron. Select all that apply. n-5, -3, m- 1, ms-1/2 At least one of your choices is incorrect. See...
