Silver atom has completely filled d orbitals (4d10) in its ground state. How can you say that it is a transition element?
The transition elements are those elements having a partially filled d or f subshell in any common oxidation state. The term "transition elements" most commonly refers to the d-block transition elements. Ag has a completely filled 4d orbital (4d10 5s1) in its ground state. Now, silver displays two oxidation states (+1 and +2). In the +1 oxidation state, an electron is removed from the s-orbital. However, in the +2 oxidation state, an electron is removed from the d-orbital. Thus, the d-orbital now becomes incomplete (4d9). Hence, it is a transition element.
The reaction between A and B is first order with respect to A and zero order with respect to B. Fill in the blanks in the following table:
| Experiment |
A/ mol L - 1 |
B/ mol L - 1 |
Initial rate/mol L - 1 min - 1 |
| I | 0.1 | 0.1 |
2.0 × 10 - 2 |
| II | -- | 0.2 |
4.0 × 10 - 2 |
| III | 0.4 | 0.4 | -- |
| IV | -- | 0.2 |
2.0 × 10 - 2 |

Step-by-step explanation:
• The transition elements are those elements having a partially filled d or f subshell in any common oxidation state
• The term "transition elements" most commonly refers to the d-block transition elements
• Ag has a completely filled 4d orbital (4d10 5s1) in its ground state
• Now, silver displays two oxidation states (+1 and +2)
• In the +1 oxidation state, an electron is removed from the s-orbital
