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.
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.*
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.
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.
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.
What is highly reactive family of elements with 7 valence electrons?
halogen
What is the 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
what elements have equal numbers of electrons and valence electrons?
hydrogen and helium
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.
What are the most reactive elements?
That would be the element with the highest atomic number but the lowest number of valence electrons.
How are the elements within row different?
They have different numbers of valence electrons.
Why are electrons so reactive?
Electrons are no reactive by itself but they are important in chemical reactions - valence electrons.
