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).

What propety is determined by the valence electrons?
This is the chemical reactivity.
What type of properties do valence elcectrons determine for an element?
Valence electrons determine the reactivity of the element.
What do these valence electrons do that make them are so important in chemistry?
the number of valence electrons determine the reactivity of the atoms
Does the electron determine the reactivity of an atom?
Outer, or valence, shell electrons do.
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.*
Reactivity of actinides?
The reactivity of actinides varies among the elements because the number of Valence Electrons in actinides have 3-6 valence electrons therefore the reactivity varies as well. -JB

Valence electrons determine the reactivity of the element.
Is the reactivity of a metal depend on how easily it loses its valence electrons?
yes it does. if the electrons are lost easily, reactivity is more.
What do these valence electrons do that make them are so important in chemistry?
the number of valence electrons determine the reactivity of the atoms
What is the reactivity of an atom determined by?
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
Does the electron determine the reactivity of an atom?
Outer, or valence, shell electrons do.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
