The inert or noble gases have a stable full outer shell of electrons which is why they are so unreactive.

What is the number of group in which the elements have a stable outer energy level?
group 18
How many electrons are in the outer energy level of group 7 a elements?
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
What do the group 17 elements become when they react with group 1 elements?
halogens have very low energy states and alkaline metals have very high (for the purposes of this I'm including hydrogen). the atom from column 1 is so energetic that it looses an electron, the one from column 17 with the with its low energy state gains an captures the electron. now both atoms are at low energies attract each other and form ionic bonds. in a compound the lower the energy state the more stable it is. so the ionic bond requires the energy to raise the alkaline metal to pre-bonded energy state.
What is the number of the group in which the elements have a filled outer energy level and are stable?
Group 18 aka the Noble Gases / Inert Gases.
When a electron returns to its stable or ground state is emits?
When an electron returns to its ground state it emits energy in the form of light.
What group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
What is the number of group in which the elements have a stable outer energy level?
group 18
What is the groups number for elements that have a stable number of electrons in their outer energy level?
Group 8
What is the most stable number of valence electrons?
The most stable number of valence electrons is 2 for hydrogen and helium, which have only one electron shell in the shell model for atomic electron configurations, and 8 for all other elements.
What is the group number for elements that have a stable number of electrons in their energy levels?
They r noble gases which have stable valance shell and grotp no. 18
What group of elements has a staple number of electrons in their outer energy level?
Group 18 elements have a stable octet.

Elements in Group 1 become more stable by what an electron?
Elements in group two become more stable as they all have complete electron shell.They do not have valence electrons and hence they are less reactive.Some of the elements of group 2 are Barium,Magnesium and Calcium
How many valance electrons do most elements need to have a stable electron configuration?
8 valance electron
Can atoms be stable when the number of protons are not equal to the number of electrons?
Yes they can be stable. That is the reason why they exist in ionic form. For example fluorine is more stable when it gains an extra electron( Number of protons are 9 Number of electrons are 10). The only elements which are stable in atomic form are Inert gases.
