Answer:
Sn and Ge
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.

Answer:
Here is a clue
Explanation:
A convenient ion exchange separation particularly designed for the separation of iron and vanadium or mangenese from cobalt has been developed for the determination of iron, cobalt and manganese or vanadium in soft magnetic alloys. After an anion exchange separation of their chloride complexes these elements are determined by a back titration of an excess of EDTA with a standard copper solution using calcein as an indicator under ultraviolet light.
