Many components of the Earth System are too small for us to comprehend. For example, atoms are too small to be seen even with the most powerful optical microscope. A sodium atom has an approximate diameter of 2 x 10-8 cm. The diameter of the period at the end of this sentence is approximately 4 x 10-4 cm.
• If you lined up sodium atoms one next to the other, how many sodium atoms would it take to span the diameter of a period? ___________ Express this number in scientific notation: ___________ •

How many orders of magnitude larger is the period than the atom? ___________

  • The number of sodium atoms would it take to span the diameter of a period is 2 x 10⁴ sodium atoms.
  • The period is larger than the atom by 4 order of magnitude.

Number of sodium atom needed to span the diameter

The number of sodium atoms would it take to span the diameter of a period is calculated as follows;

n(2 x 10⁻⁸ cm) = 4 x 10⁻⁴ cm

n = (4 x 10⁻⁴ cm) / (2 x 10⁻⁸ cm)

n = 20,000

n = 2 x 10⁴ sodium atoms

Order of magnitude the period is larger than the atom

The order of magnitude the period is larger than the atom is calculated as follows;

If 2 x 10⁴ sodium atoms is equivalent to a period, then the order of the magnitude is 4.

Thus, the period is larger than the atom by 4 order of magnitude.
