1.	Which of the following sets of quantum number is/are not possible ?
Answer» `{:(n, l , m_l , m_s),(4,4,-2,+1//2):}` `{:(n, l , m_l , m_s),(3,0,3,-1//2):}` `{:(n, l , m_l , m_s),(3,2,-3,-1//2):}` `{:(n, l , m_l , m_s),(5,3,0,+1//2):}` Solution :In OPTION (a) .l. cannot EQUAL to .n. because VALUES of .l. lie between 0,1,2,3 …. (n-1) In option (c) `m_l` cannot be - 3 for l = 2 because `m_1 =- 1` _____ 0 ______ `+ 1`
