For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
Gold is a metal that cannot displace hydrogen from dilute acid due to its low reactivity.
Noble gases are known for their low reactivity because they have a full valence shell of electrons, making them stable and less likely to form compounds with other elements.
Lead has low reactivity because it is a stable metal with a full outer electron shell. It does not readily react with other elements or compounds at moderate temperatures.
Hydrogen is infamous for its \high reactivity. The Hindenburg, which which used hydrogen as its buoyancy gas went down rapidly in flames due to the high reactivity of that hydrogen when it was ignited.
Oxygen stays as diatomic molecules in the atmosphere. These 2 oxygen atoms are bond with a double bond. So reactivity of oxygen is low.

low boiling point and high reactivity
Only in hydrogen or helium, because in these two elements only the innermost shell is also the outermost shell.
Noble gases are known for their low reactivity because they have a full valence shell of electrons, making them stable and less likely to form compounds with other elements.
Lead has low reactivity because it is a stable metal with a full outer electron shell. It does not readily react with other elements or compounds at moderate temperatures.
Low reactivity metals can easily found in earth.
High compared to hydrogen and helium, low compared to lead, gold and uranium.
It is more likely to attract electrons. :)
