1) Calculate the volume from d = m/V => V = m/d = 2.0*10^-23 g /  1.0*10^14 g/cm^3 = 2.0*10^-9 cm^3

2) Now use the formula of volume for a sphere: V = (4/3)π(r^3) =>

r =∛[3V/(4π)] = ∛[(3*2.0*10^-9 cm^3) / (4π)] = 0.48*10^-3 cm = 4.8*10^-4 cm = 0.00048cm

True

Explanation:

The position of sodium on the periodic table makes the element a solid at room temperature is very correct.

  • Sodium is an elements with 11 electrons in its shell.
  • It is located in group 1 on the periodic table because it contains an outer valence electron.
  • In a free state Na metal, the atoms exhibit metallic bonding.
  • Metallic bonding is responsible for the solid nature of this alkali metal at room temperature.
  • It is highly reactive because it has just one valence electron.
  • Metals are usually found left of the periodic table.
