Holonium and Gadolinium has the highest number of neutrons in the nucleus.

Looking at the atoms listed;

  • Dysprosium has 66 protons
  • Holonium has 67 protons
  • Neodymium has 60 protons
  • Europium has 63 protons
  • Gadolinium has 64 protons

Then,

Number of neutrons = Mass number - number of protons

  • For Dysprosium

157 - 66 = 91 neutrons

  • For Holonium

162 - 67 = 95 neutrons

  • For Neodymium

149 - 60 = 89 neutrons

  • For Europium

148 - 63 = 85 neutrons

  • For Gadolinium

159 - 64 = 95 neutrons

Hence, Holonium and Gadolinium has the highest number of neutrons in the nucleus.
