D

number of valence shell electrons and atomic radii

Answer:

A

Explanation:

beacause in both the electronegativity values and number of first she'll electrons

Answer 2

In group 14 from top to bottom there are changes in both the electronegativity values and atomic radii changes.

What are groups?

Groups in the periodic table are the columns in which elements are present which all are having same number of valence electrons.

On moving top to bottom in the 14th group of the periodic table:

• Atomic size of the elements increases and electronegativity decreases.
• Number of electrons in the first shell of all elements will be same and in the outer most shell is also same.

Hence electronegativity values and atomic radii changes.
