Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
What else can I help you with?
Elements across a series have the same number of?
valence electrons, which determine their chemical properties and how they form bonds with other elements. This shared electron configuration gives elements within the same group similar reactivity and properties.
What do elements in a group have in common?
The elements in the same group have the same number of valence electrons and hence similar chemical and physical properties.
Why do elements in group 2 have the same properties?
Elements in group 2, like beryllium, magnesium, calcium, etc., have similar properties because they all have the same number of valence electrons (2). This results in common characteristics such as reactivity and the ability to form 2+ ions.
What is the different about the valence electrons for all elements in a group?
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
What are similar chemical properties attributed to?
Similar chemical properties are attributed to elements in the same group or column of the periodic table. These elements have the same number of valence electrons, which affects their reactivity and bonding characteristics. They often form similar types of compounds and exhibit analogous chemical behaviors.
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.
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 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 are some details of the number of valence electrons in atoms affect the reactivity of elements?

Atoms of elements in a group on the periodic table have similar chemical properties this similarity is most closely related to the atoms?
having the same number of electrons in their outermost electron shell. This is known as the valence electrons, which dictate the elements' reactivity and chemical behavior. Elements in the same group tend to react in similar ways because they have the same number of valence electrons.
What does the group number of A elements in the AB numbering system tell about valence electrons?
The group number of A elements in the AB numbering system indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on. Valence electrons are important because they determine the chemical properties and reactivity of an element.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
What do you notice about the number valence electrons?
The number of valence electrons in an atom is often related to its position on the periodic table. Elements in the same group have the same number of valence electrons, which influences their chemical properties and reactivity. Valence electrons are the outermost electrons and play a crucial role in bonding with other atoms.
What is common amongst elements that have the s same number of valence electrons?
Elements with the same number of valence electrons typically have similar chemical properties. This is because valence electrons determine an element's reactivity and bonding behavior. Elements in the same group on the periodic table have the same number of valence electrons.
What do Valence Electrons determine?
Valence electrons determine the reactivity and chemical behavior of an element. Elements with the same number of valence electrons exhibit similar properties and tend to form similar types of chemical bonds.
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.*
Why do elements as a family or group share similar properties?
Elements in the same group have the same number of valence electrons, which determines their chemical properties. This leads to similarities in reactivity and chemical behavior among elements in the same group.
