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 does atomic mass indicated element reactivity?
Atomic mass does not directly indicate an element's reactivity. Reactivity is primarily determined by the number of electrons in the outer shell of an element (valence electrons). Elements with a full or nearly full outer shell (noble gases) are generally unreactive, while elements with few electrons in the outer shell (alkali metals) are highly reactive.
How many are in the outer shell of the yellow group?
There are different electrons in the outer shell of each element.
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 =)
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.
Does the electron determine the reactivity of an atom?
The number of electrons an atom has in its outer shell, and how easily those electrons can be gained or lost, determines an atom's reactivity. Electrons play a crucial role in forming chemical bonds, and the availability of electrons in the outer shell influences how likely an atom is to react with other atoms.

How easy or quickly an element combines with other substances?
This is determined by the element's reactivity. Elements that are highly reactive will easily combine with other substances, while elements with low reactivity will combine more slowly or require specific conditions to react. Reactivity is based on the element's position on the periodic table and the number of electrons in its outer shell.

Is an element's reactivity determined by the number of protons found in an atom of an element?
No, an element's reactivity is mainly determined by the number of electrons in its outer shell, known as valence electrons. Elements with fewer valence electrons tend to be more reactive as they seek to either lose, gain, or share electrons to achieve a stable electron configuration. The number of protons in an atom, which determines the element's identity, does not directly influence its reactivity.
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 element has 6 outer shell electrons?
The element with 6 outer shell electrons is carbon. Carbon has 4 electrons in its outer shell and 2 electrons in the shell before that, totaling 6 outer shell electrons.
How many electrons are in the outer shell of copper?
The outer shell (N=4) of the copper element has 2 electrons.
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?
Elements in Group 1 of the periodic table have one electron in their outer shell, while elements in Group 2 have two electrons in their outer shell. This configuration makes these elements more stable and likely to form ions with a positive charge by losing these outer electrons to achieve a full outer shell.
Does the electron determine the reactivity of an atom?
The number of electrons an atom has in its outer shell, and how easily those electrons can be gained or lost, determines an atom's reactivity. Electrons play a crucial role in forming chemical bonds, and the availability of electrons in the outer shell influences how likely an atom is to react with other atoms.
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.
