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.
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
When full the innermost electron shell of an atom contains electrons and the outemost shell contains electrons?
When full, the innermost electron shell of an atom contains 2 electrons, and the outermost shell contains 8 electrons. This is known as the octet rule, where atoms tend to gain, lose, or share electrons in order to achieve a full outer shell of 8 electrons.
Why is sodium metal highly reactive when a sodium ion is not?
In the Group 1 and Group 2 elements, these metals want to loan out electrons to achieve what is called inert gas electron configuration, which is a full outer electron shell or valence shell. Because of their electron configurations as elemental metals, they are in a big hurry to do this (they are very reactive). In the ion, the metal has already loaned an electron (in the case of the Group 1 metals) or two electrons (in the case of the Group 2 metals). As an ion, the metal is "happy" because it has already reacted and loaned out the electron or electrons that will allow it to achieve inert gas electron configuration.
Why are the halogens so reactive?
They only need 1 electron to gain a full outer shell as the Halogens are Group VII. They are very similar to the Group I metals, which, in retrospect, need to lose/give away 1 electron to achieve the same goal. This is typically why they are so reactive.
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

Is valance shell full i sodium?
No, the valence shell of sodium (Na) is not full. Sodium has an atomic number of 11, which means it has 11 electrons, with 1 electron in its outermost shell (the third shell). This single valence electron makes sodium highly reactive, as it tends to lose that electron to achieve a full outer shell, resembling the electron configuration of the nearest noble gas, neon.
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.
How many electrons would hydrogen need to have a full outer she?
Hydrogen has one electron in its outer shell and typically needs one more electron to achieve a full outer shell, which would complete its valence shell with two electrons (like helium). Therefore, hydrogen would need one additional electron to have a full outer shell.
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.
