Question

The size of the atom is of the order of (A) \(10^{-14} \mathrm{~m}\) (B) \(10^{-10} \mathrm{~m}\) (C) \(10^{-8} \mathrm{~m}\) (D) \(10^{-6} \mathrm{~m}\)

Short answer

The size of the atom is of the order of \(10^{-10} \mathrm{~m}\) (Option B).

Step-by-step solution

Eliminate choices that are too small or too large

We can first eliminate choices A and D because they are too small and too large, respectively. Atomic sizes fall somewhere in between these two extreme values.

Compare remaining choices

Next, we need to compare the remaining choices (B) and (C). In general, the size of an atom is between \(10^{-10}\) and \(10^{-9}\) meters, which is why choice (B) is the correct answer here.

Answer:

The size of the atom is of the order of \(10^{-10} \mathrm{~m}\) (Option B).
