How is the reactivity of a element releated to the outer shell?

The outer, or valence shell of electrons is closely related to an element's reactivity. First of all, the valence electrons are the only part of an atom that participate in a chemical reaction. The closer an atom's number of valence electrons is to eight (remember the octet rule), the more reactive it typically is. Elements with only 1 valence electron* (group 1) and elements with 7 valence electrons (group 17) are the most reactive. *Remember, having only 1 valence electron means once you lose it, you now have 8 electrons that were in the shell below it.*

How do you determine how reactive an element is based off its atomic number?
the reactivity of depends on the number of its outer shell electrons. one all outer shell electrons are there then there is little reactivity. If the atomic number is 19 then the element will 19 protons and 19 electrons. this means it has 2 electrons in the 1st shell 8 in the second 8 in the 3rd and 1 in the last. as it only has one it will be very reactive =)
Does the electron determine the reactivity of an atom?
Outer, or valence, shell electrons do.
How many are in the outer shell of the yellow group?
There are different electrons in the outer shell of each element.
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.
Why do noble gases such neon or argon have very low chemical reactivity?
They have very low chemical reactivity because they all have a full outer shell, i.e. they all have 8 electrons in their outer shell. This makes them very stable and thus not very reactive.

What are the Every element in group one has one electron in its outer shell Every element in group two has two electrons in its outer shell?
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
Element bromine electrons outer shell?
Bromine has 7 electrons in its outer shell.
Is an atom with an outer shell reactive?
No reactive elements always have partially filled shells- never full outer shells. Because they are partially filled they are less stable and want to react. If they had full shells they would be very stable.
Elements that are in the same have same number of electrons in the outer these outer electrons are so important in determining the chemical of an element that a special way to represent them has been?
- Electrons in the outer shell are important for the chemical reactivity of elements.- You think probable to a Lewis diagram.
The chemical properties of an atom depend on the number of what?
It depends on the number of electrons in the outer valence shell in the atom

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.
