Electronegativity is a measure of the reactivity; see the link below.
Depends on the elements with which they are reacting with.
The reactivity is increasing goinng down in the group.
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
YES!
we cant say the reactivity of H but reactivity of H can be ordered or compared with other elements. see the reactivity series
not reactive
From the elements given, argon shows the least reactivity.
inertness, non-reactivity
Depends on the elements with which they are reacting with.
It is one of the least reactive elements.
The reactivity is increasing goinng down in the group.
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
Down the group, reactivity decreases for non metals. It increases for metals.
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
group 18
YES!
