5. The ionization enthalpy of nitrogen is more than that of oxygen molecules because of
(a) greater attraction of electrons by the nucleus     (b) extra stability of the half-filled p-orbitals
(c) smaller size of nitrogen                                    (d) more penetrating effect
 
II. Fill in the Blanks
 
1. Lightest metal in s-block elements is _____________ .
 
2. Most electronegative elements belong to ___________ group.
 
3. The elements above atomic number 92 are called ___________.
 
4. The inner-transition elements belong to ________ block of the periodic table and are shown separately at the ________ of the periodic table.
 
5. Ca2+ has smaller ionic radius than K+ ion because it has ___________.
 
III. Assertion and Reasoning Questions:
 
Directions: (Questions 1 to 4).
 
A.If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
C. If Assertion is true statement but Reason is false.
D. If both Assertion and Reason are false statements.
 
1. Assertion: Ionic radius of Na+ is smaller than Na
   Reason: Effective nuclear charge of Na+ is higher than Na
 
2. Assertion: First ionization enthalpy of N is higher than O.
    Reason: Extra stability of fully filled up 2p subshell of N atom
 
3. Assertion: Electron gain enthalpy of Cl is more negative than F atom.
    Reason: F is more electronegative than Cl atom.
 
4. Assertion: First ionization enthalpy of Gallium is higher than aluminum.
    Reason: Weak shielding effect of 3d subshell is Gallium.
 
IV Descriptive Questions:
 
1. Cations are smaller than their parent atom whereas anions are larger in size than their parent atom. Explain.
 
2. Among the element of the third period, pick out the element with
a) Highest first IE                    b) Largest atomic radius
c) Most reactive non-metal       d) Most reactive metal
 
3. The reactivity of halogens decrease down the group but of alkali metals increases down the group. Why?
 
4. Which atom in each of the following pairs has greater first IE? Give reasons.
a) B or C          b) N or O           c) F or Ne          d) Cl or F       e) K or Ar    f) Kr or Xe
 
5. Electron gain enthalpy of Mg is positive. Explain.
