What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
Do noble gases have the maximum number of electrons in their outer energy level?
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
What is the word for the definition electrons in the outermost energy level of an atom?
valence electrons are the electrons in the outermost energy level
What element is a noble gas in the first energy level?
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
Are the valence electrons the outermost electrons?
Yes. Valence electrons are the electrons found in the outermost shell / energy level
How many electrons in the outermost energy level of noble gases?
8

What contains 8 electrons in the outermost energy level?
Noble gases (except for helium which has 2 valence electrons).

How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Why is krypton in the noble gases group?
Because it has it has eight electrons in the outermost occupied energy level.
What are seven electrons in the outermost energy level?
Halogens have six valence electrons in the outermost energy level.
How many electrons are in a chloride ion's outermost energy level?
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
What element is a noble gas in the first energy level?
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
How many electrons are in the outermost level of carbon how many electron does it need to have fill this energy level?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Explain how valence electrons in an atom are used to form a full outermost energy level?
The electrons on the outermost energy level of the atom are called valence electrons.
