Answer:

The order of decreasing atomic radius is bismuth, antimony, phosphorus. Number 5.

Step-by-step explanation:

The largest elements are the furthest to the left and down on the periodic table. The closer to the top right of the periodic table the smaller the element.

The atomic numbers are:

  • bismuth = 83
  • antinomy= 51
  • phosphorus = 15
