Question

Choose the one statement that is true of the noble gases.

000
A. They have a full outer shell.
B. They are solids at room temperature.
C. They react with all other elements.
OD. They are very unstable.

Answer 1

Noble gases have a full outer shell, making them highly stable and unreactive.

Step-by-step explanation:

A. They have a full outer shell.

Noble gases are a group of chemical elements that are known for their stability and lack of reactivity. They have a full complement of electrons in their outermost energy level, which makes them highly stable. This full outer shell configuration is why noble gases are unreactive and rarely form compounds.

For example, helium has two electrons in its outer shell, neon has eight, and argon has eight as well. These full outer shells make them chemically inert and stable.
