An element 'E' loses electron and becomes an ion. Name the process and ion :

Options

A. Oxidation, cation
B. Oxidation, anion
C. Reduction, cation
D. Reduction, anion

Explanation

To solve the question, we need to identify the process that occurs when an element 'E' loses an electron and determine the type of ion formed as a result. Here’s a step-by-step solution:

### Step 1: Identify the Process
When an element loses an electron, it undergoes a change in its oxidation state. Losing an electron means that the element is losing a negatively charged particle, which results in an increase in the positive charge of the atom.

**Hint:** Remember that losing electrons leads to an increase in oxidation state.

### Step 2: Define Oxidation
The process of losing electrons is referred to as oxidation. In terms of oxidation states, when an element loses an electron, its oxidation state increases. For example, if an element starts at an oxidation state of 0 and loses one electron, its oxidation state becomes +1.

**Hint:** Oxidation is associated with an increase in oxidation number.

### Step 3: Determine the Type of Ion Formed
When an element loses an electron, it becomes a positively charged ion. This type of ion is known as a cation.

**Hint:** A cation is formed when an atom loses one or more electrons, resulting in a positive charge.

### Step 4: Conclusion
Therefore, when element 'E' loses an electron, the process is called oxidation, and the ion formed is a cation.

**Final Answer:** The process is oxidation, and the ion is a cation.
