The period in the modern periodic table indicates the value of :
1. Atomic number
2. Atomic mass
3. Principal quantum number
4. Azimuthal quantum number.
Which of the following sets of quantum numbers is possible :
1. n = 0, l = 0, ml = 0, ms = + ½
2. n = 1, l = 0, ml = 0, ms = – ½
3. n = 1, l = 1, ml = 0, ms = + ½
4. n = 3, l = 3, ml = –3, ms = + ½
The total number of electrons in an atom with the following quantum numbers would be
(a) n = 4, ms = – ½
(b) n = 3, l = 0
1. 16, 2
2. 11, 8
3. 16, 8
4. 12, 7
