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.
How many electrons are in the outermost energy level of noble gases?
Helium has 2 valence electrons. All other noble gases have 8 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 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 valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
How many electrons in the outermost energy level of noble gases?
8

Which group has a complete set of valence electrons in their outermost energy level?
The noble gasses.
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 noble gases?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.

Why is krypton in the noble gases group?
Because it has it has eight electrons in the outermost occupied 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.
What element has a full set of electrons in their outermost energy level?
All of the noble gases, no other elements. Helium and Neon are 2 examples of a noble gas.
How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
Which group on the periodic table is unreactive because its outermost energy level is full?
Noble gases are unreactive with the outermost energy level full.
Why noble gases lies in eight period?
Noble gases have ns2 np6 electron configuration. They have 8 electrons in the valence shell. In addition, it is group 18 according to the modern version of periodic table.The group number of an element is equal to the number of electrons in its outermost energy level. Noble gasses has 8 electrons in that energy level. So they are in the 8th group.
