Question

Match the words in the below to the appropriate blanks in the sentences.

1. When comparing the two elements A s and S n , the more metallic element is ______based on periodic trends alone.
2. When comparing the two elements G e and S b , the more metallic element is ________ based on periodic trends alone.
A. Ge
B. Pb
C. Sb
D. impossible to determine
E. K

Answer 1

Sn and Ge

Step-by-step explanation:

To obtain the more metallic element, we compare the group in which both elements are. Generally the element with the lower ionzation energy is he more metallic one.

Ionization energy increases fro left to right across a period. Ionization energy decreases down the group.

1. When comparing the two elements A s and S n , the more metallic element is ______based on periodic trends alone.

Sn has a lower ionization energy so it is the more metallic one.

2. When comparing the two elements G e and S b , the more metallic element is ________ based on periodic trends alone.

Ge has a lower ionizaiton energy compared to Sb. So it is more metallic element than Sb.
