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.
The 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.
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
Gold has 25 valence electrons
The elements in the same group have the same number of valence electrons and hence similar chemical and physical properties.
They don't have the same number. that's what makes thme all different
Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
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

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.*
Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
Because they have the same number of valence electrons, which are the primary determinants of chemical reactivity.
All elements have same number of valence electrons (two) and hence they have similar reactivity and chemical properties.
They have the same number of valence electrons and so have similar reactivity and 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.
the number of valence electrons determine the reactivity of the atoms
yes it does. if the electrons are lost easily, reactivity is more.
Families in the Periodic Table of Elements have the same amount of valence electrons.
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
