Match the following
`{:(1. "Positively charged ions",a."Electroysis"),(2."Negatively charged ions " ,b. "Cations"),(3."Passing electric current to split a solution",c."Anions"),(4."A metal through which electric current can pass ",d."Hydrogen"),(5."Atomic number is 1",e."Electrode"):} `

Answer

To solve the matching question, we will match the items in Column A with the correct items in Column B step by step.

### Step-by-Step Solution:

1. **Positively charged ions**:
- Positively charged ions are known as **Cations**.
- **Match**: (1) "Positively charged ions" → **b. Cations**

2. **Negatively charged ions**:
- Negatively charged ions are known as **Anions**.
- **Match**: (2) "Negatively charged ions" → **c. Anions**

3. **Passing electric current to split a solution**:
- The process of passing electric current to split a solution is called **Electrolysis**.
- **Match**: (3) "Passing electric current to split a solution" → **a. Electrolysis**

4. **A metal through which electric current can pass**:
- A metal that allows electric current to pass through it is referred to as an **Electrode**.
- **Match**: (4) "A metal through which electric current can pass" → **e. Electrode**

5. **Atomic number is 1**:
- The element with atomic number 1 is **Hydrogen**.
- **Match**: (5) "Atomic number is 1" → **d. Hydrogen**

### Final Matches:
1. "Positively charged ions" → **b. Cations**
2. "Negatively charged ions" → **c. Anions**
3. "Passing electric current to split a solution" → **a. Electrolysis**
4. "A metal through which electric current can pass" → **e. Electrode**
5. "Atomic number is 1" → **d. Hydrogen**
