What are three characteristics of noble gases

Noble gases are all monatomic (single-atom molecules) and have the following characteristics under normal conditions :

  1. Odorless
  2. Colorless
  3. Low reactivity (due to a full outer electron shell)

Why do elements in the top right corner have high ionization energies

The elements in this part of the periodic table want to gain electrons to get to a noble gas configuration - not lose them. To lose electrons is very energetically unfavorable (high ionization energies).
