IF you have 2 complete full shells and no electrons any were else that means you have
2 electrons in the first shell
and 8 electrons in the second shell
which is 10 electrons in other words it is neon

Why are noble gases insert?
They have completely filled shells, with eight valence electrons (stable) and hence are inert.
Why are noble gases are non reactive?
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
What is special about the electronic structure of argon?
Argon has completely filled orbitals. It obeys octet rule (8 electrons in the valence orbitals / shells) and is stable and chemically inert
How many outer shell electros do nonmetals have?
The outermost shell of any noble gas is completely filled. And because of this, we can say that they have 8 electrons in their outer shells, with the exception of helium, which has 2 electrons in its outer shell.
How many extra valence electrons does helium need to become stable?
Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
What Atom has 2 completely filled shells and no electrons anywhere else?
Beryllium 1s^2 2s^2
What chracterizes the electron configuration of noble gases?
They have completely filled shells, with eight valence electrons.
How many electron shells would be completely filled by a neutral xenon atom how many would be left over?
5 shells filled, no electrons left over.
Why are noble gases insert?
They have completely filled shells, with eight valence electrons (stable) and hence are inert.
What is the link between noble gas and full outer shells?
Noble gases have completely filled valence electrons. Helium has 2, other elements have 8
How many electron shells would be completely filled by a neutral xenon atom?
Three electron shells would be completely filled by a neutral xenon atom.
Why metals react by losing electrons whereas halogens react by gaining electron?
Metals have a few electrons fairly loosely bound in their outer "shells", while halogens have nearly-complete outer electron "shells". The most stable configuration for an atom is to have completely-filled shells, so it's easy for metals to lose an electron or two and get down to the next "completely filled" shell, while halogens pick up extra electrons to get to the next filled shell.
How many electron shells would be completely filled by a neutral atom of calcium?
Three. The fourth shell would contain two out of a possible eight electrons.
Why are noble gases are non reactive?
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
Are atoms most stable when they have partially filled shells?
no. they are more stable when they have completely filled or half filled shells
What is special about the electronic structure of argon?
Argon has completely filled orbitals. It obeys octet rule (8 electrons in the valence orbitals / shells) and is stable and chemically inert
How many outer shell electros do nonmetals have?
The outermost shell of any noble gas is completely filled. And because of this, we can say that they have 8 electrons in their outer shells, with the exception of helium, which has 2 electrons in its outer shell.
