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.
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.
Valence electrons are the electrons that are held most loosely in an atom. These electrons are involved in chemical bonding and determine the reactivity of an element.
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.
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.
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.
That would be the element with the highest atomic number but the lowest number of valence electrons.

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.
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.
The most reactive elements have either 1 valence electron or 7 valence electrons
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.
No the most reactive have 1 or 7 - if they have 8 they are stable
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.*
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.
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.
