24. As the first five elements in Group 14 are considered in order from top to bottom, there are changes
in both the
electronegativity values and number of first shell electrons
B) electronegativity values and atomic radii
C) number of valence shell electrons and number of first shell electrons
D) number of valence shell electrons and atomic radii

Answer :

Answer:

B

Explanation:

As you move down the periodic table in the carbon family, the atomic radius and ionic radius increase while electronegativity and ionization energy decrease. Atom size increases moving down the group because an additional electron shell is added.

As the first five elements in Group 14 are considered in order from top to bottom, there are changes in both - B) electronegativity values and atomic radii.

The carbon group element, any of the six chemical elements that make up Group 14 (IVa) of the periodic table only the top 5 shows specific changes.

  1. carbon (C)
  2. silicon (Si)
  3. germanium (Ge)
  4. tin (Sn)
  5. lead (Pb)
  • The group 14 elements show the greatest range of chemical behavior of any group in the periodic table.
  • As we move down the group, the electronegativity decreases in general.
  • The atomic radii increase down the group, and ionization energies decrease.
  • Metallic properties increase down the group

Thus, As the first five elements in Group 14 are considered in order from top to bottom, there are changes in both - B) electronegativity values and atomic radii.
