What element is most reactive an en element with 7 valence electrons or an element with 8 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.

∙ 13y agoAn element whose atoms have eight valence electrons each is much less reactive, because such an element already has the energy-minimizing electron configuration, a closed octet, that other elements achieve by reaction with one another. Elements with seven electrons in each valence shell have a strong drive to abstract another one from a less electronegative atom such as a metal.

∙ 13y agoAny element with 8 valence electrons has a noble gas configuration.
So, it is very less reactive .
On the other hand, an element with 7 valence electrons will be highly reactive so as to gain one electron to have stable or noble gas configuration.

∙ 11y agoelement with 8 valence electrons have completely filled shells (orbitals) and hence are stable.
element with 7 valence electron need one more electron to get completely filled shell and hence are reactive.

∙ 11y agoYes, elements with either 1 or 7 valence electrons are super-reactive. So reactive, in fact, that they often don't even exist in nature by themselves - only in compounds. Group 1 is called the alkali metals. They quickly lose their 1 valence electron to form positive ions. Group 7 is called the halogens. They easily gain 1 valence electron to satisfy the octet rule and form negative ions.

∙ 11y agoAn element with 7 valence electrons is more reactive because all elements want to have 8 valence electrons. If an element only has 7, it can react to get to 8.

Does two valence electrons is a reactive or non reactive?
The outer shell of an atom is most stable or non reactive with 8 electrons. 1 or 2 valence electrons would be reactive. It also would depend if it's bonded with another element.
Reactivity of s-block element?
in the periodic table s block element except be and mg are highly reactive element . the reactivity increase from top to bottom and the element of lithium famil is more reactive than the the the beryllium family. cs is more reactive in s block element . they are most powerful reducing agent /
Name given to electron shell that contains the most reactive electrons?
Valence
What is the number of the prinicpal energy level in which valence electrons are found?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Electrons that are held most loosely in an atom are called what?
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
Does two valence electrons is a reactive or non reactive?
The outer shell of an atom is most stable or non reactive with 8 electrons. 1 or 2 valence electrons would be reactive. It also would depend if it's bonded with another element.
What are the most reactive elements?
That would be the element with the highest atomic number but the lowest number of valence electrons.
What happens to the reactivity of metals from left to right across the perriodic table?
Elements become less reactive as you move from left to right across the periodic table. This is due to how many valence electrons (outer-most electrons) the element has; the less valence electrons, the more reactive the element.
Are having eight valence electrons makes atoms very reactive?
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
Which atoms are most reactive?
The most reactive elements have either 1 valence electron or 7 valence electrons
What is the electron shell that contains the most reactive electrons?
No electrons are reactive. Electrons can, under the huge majority of circumstances, only be removed starting from the outermost, working inwards.
Why is the halogen group fairly unusual?
It really isn't unusual....it is unique in that the elements have seven valence electrons and all are rather reactive; especially fluorine, which is the most reactive element.
Do the most reactive atoms already have 8 valence electrons?
No the most reactive have 1 or 7 - if they have 8 they are stable
Reactivity of s-block element?
in the periodic table s block element except be and mg are highly reactive element . the reactivity increase from top to bottom and the element of lithium famil is more reactive than the the the beryllium family. cs is more reactive in s block element . they are most powerful reducing agent /
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.*
