Roughly, first ionization potential and electron affinity.
Electronegativity is a measure of the reactivity; see the link below.
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.
Depends on the elements with which they are reacting with.
This property is called chemical reactivity.
Elements in the same family have similar chemical properties because they have the same number of outer electrons, which determines their reactivity. This similarity is due to the elements in a family occupying the same column on the periodic table, which means they share the same number of valence electrons.
The number of electrons in an element determines its chemical properties and behavior. Specifically, it influences how an element will bond with other elements to form compounds and determines its reactivity.
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.
not reactive
Electronegativity is a measure of the reactivity; see the link below.
Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.
inertness, non-reactivity
Depends on the elements with which they are reacting with.
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 capacity of elements to displace hydrogen can be determined based on their position in the reactivity series. Elements higher in the reactivity series can displace hydrogen from compounds of elements lower in the series. For example, metals like magnesium and zinc can displace hydrogen from water because they are higher in the reactivity series.
This property is called chemical reactivity.
In the chemical reactivity of atoms electrons are involved.
Elements are organized into families on the periodic table based on their similar chemical properties. Elements in the same family have the same number of valence electrons, which determines their reactivity and chemical behavior. This organization helps scientists predict the properties of unknown elements based on their location in the periodic table.
