When comparing the two elements K and Ge , the more metallic element is based on periodic trends alone. When comparing the two elements Sb and Pb , the more metallic element is based on periodic trends alone.

a. Ge
b. Pb
c. Sb
d. K
e. Impossible to determine

Option D and Option B

When comparing the two elements K and Ge , the more metallic element isK based on periodic trends alone.

When comparing the two elements Sb and Pb , the more metallic element isPb based on periodic

Explanation:

The metallic characteristic increases when we move down a column in a periodic table or when we move left in the row.

Potassium and Germanium are located on the same row, but germanium lies on the right side of potassium. Thus, potassium (K) is more metallic than Germanium (Ge)

While Lead (Pb) lies to left of Sb in the adjacent column and is also lies below Sb. Hence Pb is more metallic than Sb
