Question

Match the atoms which might substitute for one another. Match the items in the left column to the items in the right column.

1. Si A. Na
2. K B.V
3. Nb C.C
4. Cu D.Ag
5. P E.Ca
6. Mg F.As

Answer 1

1. Si = C.C

2. K = A. Na

3. Nb = B. V

4. Cu = D. Ag

5. P = F. As

6. Mg = E. Ca

Step-by-step explanation:

Answer 2

If you want to answer this question, all you have to do is take a look at the periodic table. An element might substitute for another element if it is from the same family/column on the periodic table.
So, these are the atoms which might substitute for one another:
1. Si = C.C
2. K = A. Na
3. Nb = B. V
4. Cu = D. Ag
5. P = F. As
6. Mg = E. Ca
