How does the number of valence electrons affect the reactivity of an atom?

atoms are most stable when they have filled the outer shell of electrons which normally holds a max of 8. so if an atom has 1 electron in its outer layer getting rid of it will give him stability, in much the same way having 7 electrons will mean gaining one electron will give it stability. now lets say the two meet, they react with each other and everybody is happy.
It is thought than when two elements react, they are trying to acheive a "perfect" electronic configuration (i.e. have a full outer shell). The more electrons needs to lose/gain before acheiving this stability determines its reactivity.

∙ 12y agoIn order for an atom to be "happy" it will want to completely fill it's outer orbital withelectrons. For example, if the outer orbital of an atom can hold up to 8 electrons, but only has 2, it's going to be very reactive because it wants 6 more electrons. Now if you have the same orbital with 6 electrons it's going to be less reactive because it will need only 2 electrons to become happy.

∙ 13y agoelectrons differ in the amount of energy they have and how tightly they are held by the protons in the nucleus. Based on these properties, chemists describe an atom's electrons as belonging to certain energy levels. Usually it is the electrons in the highest energy level of an atom that determine how that atom reacts.

Only for nonmetals, for metals the most reactive are to the left and have 1 valence electron. Nonmetals have many, 6 or 7, valence electrons that make them very reactive.

This makes the element neutral. If you added a negatively charged electron then the whole atoms charge would be changed and thus, the reactivity is changed.

What is the different about the valence electrons for all elements in a group?
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
How is the reactivity of elements related to valence electrons in atoms?
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
What property of an element does the group number identify in a numbering system that uses a and b?
The number of valence electrons. :) have a good day breh
State the number of valence electrons in an atom of calcium?
A calcium atom has two valence electrons.
Elements across a series have the same number of?
They don't have the same number. that's what makes thme all different
What are some details of the number of valence electrons in atoms affect the reactivity of elements?

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
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
What do Valence Electrons determine?
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
What determines the reactive of an element?
The number of valence electrons determines reactivity. Valence electrons are the number of electrons in outermost shell.
What is the reactivity of an atom determined by?
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
How are valence electrons differ from other electrons in an atom?
The closer the number of valence electrons is to the number required to completely fill or deplete its outer shell the more likely the atom is to react. With other electrons in an atom the shells are full and they have little if any affect on the reactivity of an atom. Valence electrons are the only electrons that are available to be shared/transferred in a bond.
The reactivity of an atom arises from what?
the existence of unpaired electrons in the valence shell. :)
What is the difference between the atomic number of an element and number of valence electrons?
Describe the reactivity of halogens
What is the difference between the atomic number of an element and the number of valence electrons?
Describe the reactivity of halogens
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
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
