What else can I help you with?
What is special about the electron configurations of all noble gasses?
The electron configuration of the noble gasses are such that the valence shell (the outer most shell of electrons) is filled up with eight electrons. the outermost shell of electrons can only fit eight and the noble gasses already have all eight.
Are the outer electron shells always filled first?
No. The inner shells are filled first.
Why are noble gases chemically inactive?
The noble gasses all have a filled outer electron shell of eight electrons, except helium which has two electrons. Since their outer electron shells are filled, they are less likely to react with other atoms.
When an atom's outer layer is filled with electron it is?
Atoms whose outer shell is filled have eight valence electrons and belong to Group XVIII. This group is known as the noble gases.
Why are noble gasses are so unreactive?
Noble gases have completely filled outer electronic configuration. Hence they are non-reactive.
Is sodiums outer shell complete?
No. It has one electron which is readily lost to produce the Na+ ion. Note - the ONLY elements with a complete outer shell are the noble gasses.
How many electron shielding layers do noble gasses have?
Noble gases have 8 electron shielding layers. This is because noble gases have a full outer electron shell, so they have filled all available energy levels up to the 8th shell, leading to 8 electron shielding layers.
How many electrons are in the outer shell of sodium lithium and potassium?
Lithium and potassium are both alkali metals. Thus their outermost orbitals are filled up to s1. So, that shows us that they both have only one outer level electron each.
If an element is chemically active what is the state of its outer electron shell?
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
Why are the noble gasses non-reactive?
The noble gasses are unreactive because of the elctronic structure. On the outer shell of the noble gasses there is no electrons to be shared because it is full. a reaction is caused by an electron jumping from the outer shell of one element to the outer shell of the other.
Does a partially filled outer electron level make an atom stable?
A partially filled outer electron level does not necessarily make an atom stable. Stability often depends on achieving a full outer electron level through gaining, losing, or sharing electrons to reach a stable configuration, such as the octet rule for main group elements.
What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
