The noble gases are unreactive and stable. Which of the following explains why this is true?
They have 8 electrons in their outer shell (except for Helium).
They exist on their own without other elements.
They have more electrons than other elements.
They each have no electrons.

EXPLAIN

Respuesta :

Answer:

The answer is A. They have 8 electrons in their outer shell (except for Helium).

Explanation: This is because of the number of valence electrons( the amount of electrons in their outer shell). For a reaction to take place, a transfer of electrons must take place. If their outer shell is already full, they don't have any tendencies to react.

Noble gases are unreactive gases and are stable. This is because they have complete octet or eight electrons in their outer shells. Thus, option A is accurate.

What are noble gases?

Noble gases are the gases of the periodic table that do not show any reaction with other elements and have great stability and low reaction rates.

They are special as their outermost orbit is completely filled to complete their octet rule so they lack any free electron to take part in a chemical reaction.

Therefore, option A. noble gases have eight electrons in their outermost shell.
