Calculate the planar density of the \( (100) \) plane of a simple cubic crystal structure. Your answer should be in units of atoms \( / \mathrm{pm}^{2} \), where pm is picometer. Assume an atomic radius (R) of \( 100 \mathrm{pm} \). Provide and round up your answer in scientific notation (x.xx) using 2 decimal point accuracy. For Example: if your answer is \( 1.2345 \times 10^{-5} \) atoms \( / \mathrm{pm}^{2} \). JUST WRITE \( 1.23 \) in the box. if your answer is \( 1.2355 \times 10^{-5} \) atoms \( / \mathrm{m}^{3} \). JUST WRITE \( 1.24 \) in the box.
