Question

Which of the following is a property of the elements classified as Noble Gases?
They are the same element.
They combine easily with other atoms.
They are metallic elements.
They have their outer shell of electrons completely filled.

Answer 1

Properties of noble gases:
The noble gases are relatively nonreactive. This is because they have a complete valence shell. They have little tendency to gain or lose electrons. The noble gases have high ionization energies and negligible electronegativities. The noble gases have low boiling points and are all gases at room temperature..


Summary of common properties:
Fairly nonreactive
Complete valence shell
High ionization energies
Very low electronegativities
Low boiling points (all gases at room temperature)
