Elements that have one or two valence electrons are generally the most reactive. For example, alkali metals (like lithium, sodium, and potassium) have one valence electron, making them highly reactive as they tend to lose that electron easily. Similarly, alkaline earth metals (like magnesium and calcium) with two valence electrons are also quite reactive, as they readily lose both electrons to achieve a stable electron configuration. The reactivity decreases with increasing valence electrons, especially in nonmetals.

Why are electrons so reactive?

Electrons are no reactive by itself but they are important in chemical reactions - valence electrons.


A group of element that has 2 valene electrons are called what?

A group of elements with two valence electrons are called alkaline earth metals. This group includes elements like magnesium and calcium. These elements are highly reactive due to their tendency to lose their two valence electrons.


Which elements are likely to be the least reactive based on the numbers of valence electrons?

Elements that are likely to be the least reactive are those found in Group 18 of the periodic table, known as the noble gases. These elements, such as helium, neon, and argon, have a full outer shell of valence electrons (eight, in most cases), making them stable and less likely to engage in chemical reactions. Additionally, elements with a full outer shell, like the alkaline earth metals in Group 2, are also generally less reactive than those with fewer valence electrons.


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.

Do noble gases have valence shells?

Yes they have eight electrons in their valence shells. This is why they are not reactive. All elements have valence shells.


The most reactive elements have how many valence electrons?

The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.


Which atoms are most reactive?

The most reactive elements have either 1 valence electron or 7 valence electrons


Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?

the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.


What determines the reactive of an element?

The reactivity of an element is determined by its number of valence electrons. Elements with fewer valence electrons tend to be more reactive as they seek to gain electrons to achieve a stable electron configuration. Additionally, factors such as electronegativity, atomic size, and the presence of nearby elements can also influence an element's reactivity.


How many valence electrons do alkaline earth metals have?

The alkali earth elements have TWO valence electrons.

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.
