Answer :
(1) The correct option is, (b) orbital shape.
(2) The correct option is, (d) 8
(3) The correct option is, (c) 2
Explanation :
Part 1 :
As we know that there are four quantum numbers :
Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as [tex]m_l[/tex]. The value of this quantum number ranges from [tex](-l\text{ to }+l)[/tex]. When l = 2, the value of [tex]m_l[/tex] will be -2, -1, 0, +1, +2.
Spin Quantum number : It describes the direction of electron spin. This is represented as [tex]m_s[/tex] The value of this is [tex]+\frac{1}{2}[/tex] for upward spin and [tex]-\frac{1}{2}[/tex] for downward spin.
As per question, the letter "p" is the symbol [tex]4p^3[/tex] indicates the shape of the orbital.
Hence, the correct option is (b) orbital shape.
Part 2 :
Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.
Number of electrons in an atom are determined by the electronic configuration.
The element oxygen belongs to group 16 and atomic number 8.
As per question the electronic configuration of oxygen atom will be,
[tex]1s^22s^22p^4[/tex]
The total number of electrons = [2 + 2 + 4] = 8
Hence, the correct option is (d) 8
Part 3 :
The element sulfur belongs to group 16 and atomic number 16.
As per question the electronic configuration of sulfur atom will be,
[tex]1s^22s^22p^63s^23p^4[/tex]
In 3p orbital there are 4 electrons and 'p' orbital can contain 6 electrons. So, the number of paired electrons and unpaired electrons will be 2 and 2 respectively.
Hence, the correct option is (c) 2
