Is the outer energy level of a noble gas filled?

Yes. it is filled.


How many electrons are in the outer energy level of xenon?

There are 8 electrons in the outer energy level of xenon. Xenon belongs to the noble gas group on the periodic table, which have a full outer energy level with 8 electrons.


What a gas in the rightmost column of the periodic table with a full outer energy level?

Noble gases are the gases in the rightmost column of the Periodic Table that have a full outer energy level. This is why the noble gases do not react with other elements readily. When an atom has a full outer energy level, it means that it has the maximum number of electrons in these outer shells, making it stable.


How many electrons does a chemically stable atom have in its outer energy level?

Which elements have full outer energy levels?

All of the Noble Gases, which are on the right side of the periodic table, have a full outer energy level. The elements that are Noble Gases are the following: Neon Argon Krypton Xenon Radon Ununoctium


The noble gas distribution for the element chlorine are?

The noble gas distribution for chlorine (Cl) is 2,8,7. This means it has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level. Chlorine achieves stability by gaining one electron to complete its outer energy level to achieve the same electron configuration as argon, a noble gas.


An element that is considered to be unreactive because it has a filled outer energy level is?

A noble gas is considered unreactive because it has a filled outer energy level. The full outer energy level provides stability and low reactivity, as the element does not need to gain or lose electrons to achieve a stable electron configuration.


Which noble gas does not have eight electrons in it's highest occupied energy level?

Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.


Is a noble gas such as helium tends not to form compounds with other elements its outer energy level is missing two electrons?

Correct, noble gases such as helium have full outer energy levels and are stable, making them unlikely to form compounds with other elements. In the case of helium, it has only two electrons in its outer energy level, fulfilling the octet rule without the need to gain or lose electrons.


A noble gas such as helium tends not to form compounds with other elements because its outer energy level is missing two electrons true or false?

FALSE.


How many electrons are in the second energy level of neon?

Neon is a noble gas, therefore it is stable meaning that its outer energy ring is full. It has 8 elections on its outer energy level. Check out the related link for a picture of a model of Neons atom.
