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

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.

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.

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.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
