Well, either a high amount or a low amount. Take the alkali metals for example. They all have just one valence electron and they need to lose it to fulfill the octet rule. That is what makes them so reactive; they will combine with any element in order to lose that one electron. They all have a low ionization energy, meaning it takes a relatively small amount of energy to knock off that lone electron, whereas other elements have to lose more electrons.
This also applies to elements with a lot of valence shell electrons, such as fluorine which only needs one more electron to fulfill the octet rule. This is another element that will react with almost anything because it doesn't take much for it to "get what it wants".
What else can I help you with?
If an element has a total of 86 electrons is it inert reactive or non reactive?
An element with 86 electrons is reactive because it is not a noble gas and does not have a full outer electron shell. Elements tend to react to achieve a stable electron configuration, such as by gaining or losing electrons to achieve a full outer shell.
How many electons are contianed in the outer shell of each element in group 1?
Elements in group 1 have 1 electron in their outer shell. This single electron gives them a valency of 1 and makes them highly reactive.
What is the characteristics about the outer electron shells of halogens?
The outer electron shells of halogens have seven electrons, making them one electron short of a full outer shell. This makes halogens highly reactive as they tend to gain an electron to achieve a stable electron configuration. Halogens are located in Group 17 of the periodic table.
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.
An electron configuration that is not chemically reactive?
Where there are 8 electrons in the outer shell so a full shell. Elements are reactive when they need to lose or gain an electron. The noble gases are unreactive as they have a full outer shell.

What element has a complete valence electron shell?
An element with a complete valence electron shell is a noble gas. Noble gases have a full outer electron shell, making them stable and non-reactive. Examples include helium, neon, and argon.
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 electons are contianed in the outer shell of each element in group 1?
Elements in group 1 have 1 electron in their outer shell. This single electron gives them a valency of 1 and makes them highly reactive.
Why is rubidium reactive?
because it only has one electron on its outer shell

When an electron moves from the outer shell of one element to the outer shell of another element what kind of bond has been created?
This is an ionic bond.
Is the chlorine atom stable?
Yes, the chlorine atom is stable. It has a full outer electron shell with 8 electrons, making it a highly reactive and stable element.
Is a chlorine atom stable even if it has seven atoms in the outer third shell?
No. Chlorine's electron configuration is unstable. As a result, chlorine is a highly reactive element.
What groups is reactive and gain one electron to have a full outer shell?
group 7
