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.
How many electrons does chlorine need to gain to have a full outer shell?
Chlorine needs to gain one electron to have a full outer shell and achieve a stable electron configuration.
Will chlorine gain an electron?
Chlorine atoms have 7 outermost electrons and need to gain an electron to achieve the stability of a full valence shell.
What is the electron arrangement of nickel?
Electron Arrangement for Nickel: 1s22s22p63s23p63d84s2 the electron orbital arrangement in terms of increasing energy however is 1s22s22p63s23p64s23d8. Using the "noble gas core" method the arrangement can also be written [Ar]3d84s2. The arrangement for Ni2+: 1s22s22p63s23p63d8
How many electrons does sodium need to loss to get a full outer shell?
Sodium has 1 electron in its outer shell, and it needs to lose that one electron to achieve a full outer shell (valence shell) with 8 electrons. By losing this one electron, sodium will achieve a stable electron configuration similar to that of the noble gas neon.
Is the outer shell of nickel full?
The outer shell of nickel is not full. Nickel has an electron configuration of 4s2 3d8, so its outer shell has two electrons which is not the maximum it can hold (which would be 8).
Does lithium have a full outer shell?
no it only has 1 electron in the outer shell

Does Sodium have a full outer valence shell?
Sodium does not have a full outer valence shell. It has one electron in its outermost shell, which makes it very reactive and likely to lose that electron to achieve stability.
When a valance shell has 7 electrons will it gain or lose an electron?
It will gain an electron so that it can complete a full outer shell of 8 electrons.
How many electrons does chlorine need to gain to have a full outer shell?
Chlorine needs to gain one electron to have a full outer shell and achieve a stable electron configuration.
How many electrons does potassium need to loss to get a full outer shell?
Potassium needs to lose 1 electron to achieve a full outer shell, as it has 1 electron in its outermost shell. By losing this electron, potassium can achieve the stable electron configuration of the nearest noble gas, argon.
How many more valence electrons does sodium need to have a full?
Sodium would need to gain 7 electrons to fill its valance shell. Instead of doing that, however, sodium will lose the one valence electron it does have, leaving behind the shell below it, which is already full.
Will chlorine gain an electron?
Chlorine atoms have 7 outermost electrons and need to gain an electron to achieve the stability of a full valence shell.
Chlorine will tend to lose all of its seven outer electron or gain one electron?
Chlorine will tend to gain one electron to achieve a stable electron configuration with a full outer shell. This results in the formation of the chloride ion, which has a full outer shell of electrons.
How can you get an ion of bromine?
Bromine has 7 electrons in its outer shell and needs to gain one electron to have a full outer shell and become an ion. It will gain this electron from an atom that has one electron in its outer shell such as Lithium or Sodium.
