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.
In 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.
electrons 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.
The more to the right of the Periodic Table the more reactive
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.
All electrons in the atom of any element determine the reactivity. In potassium for example: it has 19 protons with a positive charge 19 electrons with a negative charge. 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.
These are the only electrons available to form bonds so bonding is dependent on the number of electrons in the outermost shell.
how does the number of valence electrons affect the reactive of an atom
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
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.
The number of valence electrons. :) have a good day breh
A calcium atom has two valence electrons.
They don't have the same number. that's what makes thme all different

the number of valence electrons determine the reactivity of the atoms
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
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.
The number of valence electrons determines reactivity. Valence electrons are the number of electrons in outermost shell.
It's determine by the vacancy (unfilled orbital) in the outermost shell of 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 existence of unpaired electrons in the valence shell. :)

It depends on the number of electrons in the outer valence shell in the atom
