The radius of the atom is of the order of

Options

A. `10^(-8)m`
B. `10^(-9)m`
C. `10^(-11)m`
D. `10^(-10)m`

Answer

To determine the order of the radius of an atom, let's analyze the information step by step.

### Step 1: Understand the size of an atom
Atoms are the basic units of matter and have sizes that can be measured. The typical size of an atom is on the order of magnitude of 10^-10 meters.

### Step 2: Compare the given options
We have four options to choose from:
1. \(10^{-8}\) meters
2. \(10^{-9}\) meters
3. \(10^{-11}\) meters
4. \(10^{-10}\) meters

### Step 3: Identify the correct order of magnitude
From our understanding, the radius of an atom is approximately \(10^{-10}\) meters, which is also referred to as 1 angstrom.

### Step 4: Select the correct option
Among the provided options, option 4, which states \(10^{-10}\) meters, matches the known order of the radius of an atom.

### Conclusion
Thus, the radius of the atom is of the order of \(10^{-10}\) meters.

### Final Answer
The correct option is **4. \(10^{-10}\) meters**.
