Why are electrons so reactive?
Electrons are no reactive by itself but they are important in chemical reactions - valence electrons.
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
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?
No electrons are reactive. Electrons can, under the huge majority of circumstances, only be removed starting from the outermost, working inwards.
If an atom contains 17 protons and 7 valence electrons what can you determine about the elements and its levels of reactivity?
This element is chlorine and is very reactive.
What is the highly reactive family of elements with 7 valence electrons.?
halogen
What is highly reactive family of elements with 7 valence electrons?
halogen
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.
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.
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.
Valence electrons determine an atoms what?
They tell you how reactive the element is. If the atom has only one electron, then it is highly reactive. If the valence shell is full, then it will not react with other elements.
Why are electrons so reactive?
Electrons are no reactive by itself but they are important in chemical reactions - valence electrons.
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.
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.
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.
