Roughly, first ionization potential and electron affinity.

Electronegativity is a measure of the reactivity; see the link below.
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.
This property is called chemical reactivity.
The reactivity is increasing goinng down in the group.
The number of loosely held electrons determines the reactivity of an element. Other elements attract electrons and will react also.
By using the activity series (sometimes called reactivity series) which orders metals by their reactivity with other metals, one can determine the reactivity of a metal
we cant say the reactivity of H but reactivity of H can be ordered or compared with other elements. see the reactivity series
total number of electrons
not reactive
From the elements given, argon shows the least reactivity.
Electronegativity is a measure of the reactivity; see the link below.
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.
It is one of the least reactive elements.
In the chemical reactivity of atoms electrons are involved.
