3. Why does the Ionisation energy support the trend for Group 2?

  • The ionisation energy increases, so they lose electrons more easily
  • The ionisation energy decreases, so they lose electrons more easily
  • The ionisation energy decreases, so they gain electrons more easily
  • The ionisation energy increases, so they gain electrons more easily
