Valence electrons are the electrons on the outer shell of an atom. Valence electrons help to determine the reactivity of a substance because atoms do their best to "fill" their outer shell with 8 electrons, thus achieving a more stable energetic state.
Different atoms have different numbers of valence electrons, which affects their reactivity.
For instance, noble gases are inert because they possess a full set of valence electrons and don't need to "borrow" or "give away" electrons to have a full outer shell.
Halogens, on the other hand, are 1 electron away from filling their outer shell, and are very reactive as a result (they attempt to "borrow" an electron with other atoms by forming a chemical bond).

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 is an elements most likely state related to its valence electrons?
An element's most likely state is related to its valence electrons because valence electrons determine an element's reactivity and ability to form chemical bonds. Elements with a full valence shell are stable and often found in a solid state, while elements with incomplete valence shells are more reactive and tend to form compounds in order to achieve a stable electron configuration.

Is the reactivity of a metal depend on how easily it loses its valence electrons?
Yes, the reactivity of a metal does depend on how easily it loses its valence electrons. Metals that lose electrons easily are more reactive because they can form positive ions more readily. This is why alkali metals, which have only one valence electron, are highly reactive.

What is the reactivity of an atom determined by?
The reactivity of an atom is determined by the number of electrons in its outer energy level (valence electrons). Atoms with incomplete valence shells tend to be more reactive as they seek to gain, lose, or share electrons to achieve a stable electron configuration. Electrons in the outermost energy level are involved in chemical reactions.
What do you notice about the number valence electrons?
The number of valence electrons in an atom is often related to its position on the periodic table. Elements in the same group have the same number of valence electrons, which influences their chemical properties and reactivity. Valence electrons are the outermost electrons and play a crucial role in bonding with other atoms.

What do Valence Electrons determine?
Valence electrons determine the reactivity and chemical behavior of an element. Elements with the same number of valence electrons exhibit similar properties and tend to form similar types of chemical bonds.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
