Positive oxidation state of an element indicates that it is -

Options

A. Is in elementry form
B. Oxidised
C. Reduced
D. Does not changed.

Answer

To solve the question "Positive oxidation state of an element indicates that it is," we will analyze the concept of oxidation states and their implications step by step.

### Step-by-Step Solution:

1. **Understanding Oxidation State**:
- The oxidation state (or oxidation number) of an element in a compound indicates the degree of oxidation (loss of electrons) of that element.

2. **Positive Oxidation State**:
- A positive oxidation state means that the element has lost one or more electrons. This loss of electrons results in a net positive charge, which is characteristic of cations.

3. **Oxidation Process**:
- The process of oxidation is defined as the loss of electrons. When an element is oxidized, it transitions from a neutral state (where it has an equal number of protons and electrons) to a positively charged state by losing electrons.

4. **Conclusion**:
- Therefore, if an element has a positive oxidation state, it indicates that the element has been oxidized.

5. **Choosing the Correct Option**:
- Based on the above reasoning, we can conclude that the correct answer to the question is that a positive oxidation state indicates that the element is oxidized.

### Final Answer:
- The positive oxidation state of an element indicates that it is **oxidized**.
