Answer 1

A.) Have a full outer electron shell

Step-by-step explanation:

Answer 2

Answer;

A. have a full outer electron shell

Explanation;

• Noble gases are elements that are found in Group 18 of the periodic table. They include, Neon, Argon, Krypton, Xenon, etc.
• The outer shell of valence electrons is considered to be “full” in noble gases, giving them little tendency to participate in chemical reactions. This means they have an octet configuration.
• They are all monatomic gases under standard conditions, including those with larger atomic masses than many other elements that are solids under standard conditions.
