13. Base your answer to the following question on the information below and on your knowledge of chemistry.
ahrayia [7]

From our knowledge of periodic trends, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.

<h3>Periodic trends</h3>

The periodic trends are those properties that increase or decrease down the group or across the period. These periodic trends include;

  • Ionization energy
  • Electron affinity
  • Atomic radius
  • Ionic radius etc

As more shell are added down the group in group 14, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.

The radius of an atom of gold (Au) is about 1.35 Å.
Eduardwww [97]
Two radius of an atom is equal to the diameter. Adding up all the diameter of  the atoms, it should be equal to 9.5 mm. Therefore, we simply convert the units to the same units then divide 1.35 A to 9.5 mm. We calculate as follows:

no. of atoms = 0.0095 m / 1.35x10^-9 m = 7037037 atoms 

Hope this answers the question. Have a nice day.
