How is the reactivity of elements related to valence electrons in atoms?

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.

∙ 7y agoThe number of valence electrons in an atom of an element determines many properties of that element, including the ways in which the atom can bond with other atoms.

What is the different about the valence electrons for all elements in a group?
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
How many valence electrons do each what elements have boron gold krypton and calcium?
Gold has 25 valence electrons
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.
Elements across a series have the same number of?
They don't have the same number. that's what makes thme all different
How many valence electrons does an atom have from group 16?
Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
Reactivity of actinides?
The reactivity of actinides varies among the elements because the number of Valence Electrons in actinides have 3-6 valence electrons therefore the reactivity varies as well. -JB
What are some details of the number of valence electrons in atoms affect the reactivity of 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.*
How did the periodic table get its name?
Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
Why do elements in the family have similar properties?
Because they have the same number of valence electrons, which are the primary determinants of chemical reactivity.
What do the elements in oxygen family have in common?
All elements have same number of valence electrons (two) and hence they have similar reactivity and chemical properties.
What is true about elements in each groups?
They have the same number of valence electrons and so have similar reactivity and similar properties.
Why do elements in the same group or column of the periodic table have similar properties?
Elements in the same column on the periodic table have similar chemical reactivity because they have the same outer electron configuration and it is the electron structure that determines an elements properties.
What do these valence electrons do that make them are so important in chemistry?
the number of valence electrons determine the reactivity of the atoms
Is the reactivity of a metal depend on how easily it loses its valence electrons?
yes it does. if the electrons are lost easily, reactivity is more.
What do the families in the periodic table have in common?
Families in the Periodic Table of Elements have the same amount of valence electrons.
What is the reactivity of an atom determined by?
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
