high reactivity


strong odor


brightly colored


low reactivity

Answer 1

The answer is LOW REACTIVITY

Answer 2

'Low reactivity' is common property of noble gases.

Step-by-step explanation:

The properties of noble gases are:

• They are colorless, odorless and mono atomic gases.
• They are found in group number 18 of the modern periodic table.For example ; helium , xenon etc.
• They have completely filled
  `ns^2np^6` electronic configuration in their valence shells which accounts for their inert nature and low reactivity.
• They have high ionization enthalpies.
• The electron gain enthalpies of noble gases are positive.
