200
I contain the most stable outer shell, and I am a group of inert gases.
What are noble gases?
200
This is a chemical reaction where heat is released in to the surroundings.
What is an exothermic reaction?

What is a molecule?
400
If I take an electron, my charge becomes this.
What is negative?
400
I am an element that is highly reactive alkali metal, but when I pair with chlorine I become salt.
