Atomic no. of X,Y &Z are 33,53 &83 respectively.

Options

A. X & Z are non-metal & Y is metal
B. X ia metalloid, Y is non-metal & Z is metal
C. X & Z are metals , Y is non-metal
D. None of these

Answer

To solve the question regarding the classification of elements based on their atomic numbers, we will follow these steps:

### Step 1: Identify the Elements
- The atomic numbers provided are:
- X = 33
- Y = 53
- Z = 83

### Step 2: Find the Elements Corresponding to the Atomic Numbers
- Using the periodic table, we can identify the elements:
- Atomic number 33 corresponds to Arsenic (As).
- Atomic number 53 corresponds to Iodine (I).
- Atomic number 83 corresponds to Bismuth (Bi).

### Step 3: Classify Each Element
- Now, we classify each element based on their properties:
- **Arsenic (As)**: This element is a metalloid. Metalloids have properties of both metals and non-metals.
- **Iodine (I)**: This element is a non-metal. Non-metals are generally poor conductors of heat and electricity.
- **Bismuth (Bi)**: This element is a metal. Metals tend to lose electrons and conduct electricity.

### Step 4: Summarize the Classifications
- Based on the classifications:
- X (Arsenic) is a metalloid.
- Y (Iodine) is a non-metal.
- Z (Bismuth) is a metal.

### Step 5: Match with Given Options
- The options provided in the question are:
1. X and Z are non-metals, Y is metal.
2. X is metalloid, Y is non-metal, Z is metal.
3. X and Z are metals, Y is non-metal.
4. None of these.

- The correct classification matches option 2: "X is metalloid, Y is non-metal, Z is metal."

### Final Answer
The correct answer is option 2: X is metalloid, Y is non-metal, Z is metal.
