What element is most reactive an en element with 7 valence electrons or an element with 8 valence electrons?
An 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.
What else can I help you with?
Does two valence electrons is a reactive or non reactive?
Two valence electrons make an atom chemically reactive because it wants to either gain or lose electrons to achieve a full valence shell. This makes it more likely to form bonds with other atoms to reach a stable electron configuration.
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.
Name given to electron shell that contains the most reactive electrons?
The outermost electron shell is called the valence shell. It contains the most reactive electrons because these electrons are farthest from the nucleus and are more likely to interact with other atoms to form chemical bonds.
What is the number of the prinicpal energy level in which valence electrons are found?
The principal energy level in which valence electrons are found is the highest energy level of an atom. Valence electrons are the electrons in the outermost energy level of an atom, which is also referred to as the valence shell.
Is valence electrons in the outer most orbital?
Yes, valence electrons are the electrons in the outermost energy level or orbital of an atom. These electrons are involved in determining the chemical properties of an element and its ability to bond with other atoms.
What are the most reactive elements?
That would be the element with the highest atomic number but the lowest number of valence electrons.
Does two valence electrons is a reactive or non reactive?
Two valence electrons make an atom chemically reactive because it wants to either gain or lose electrons to achieve a full valence shell. This makes it more likely to form bonds with other atoms to reach a stable electron configuration.
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
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
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.*
What is the electron shell that contains the most reactive electrons?
The outermost electron shell, known as the valence shell, contains the most reactive electrons. These electrons are involved in chemical reactions and interactions with other atoms to achieve a stable electron configuration, usually by gaining, losing, or sharing electrons.
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.
What time describes the most reactive nonmetals that have seven valence electrons?
Halogens
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.
