Yes, all the metals are reactive but the differences in reactivity are very important.
Halogens: fluorine, chlorine, bromine, iodine, astatine.
Also oxygen and hydrogen are reactive.
It varies. The further right the non metal is on the periodic table, the more reactive it is.
Group 17, or halogens, are the most reactive nonmetals.
Yes, except for the noble gases.
The reactivity is increasing, from left to right - for example halogens.
No. The most reactive non metal, fluorine, has the highest electron affinity.
Semi-metals (or metalloids) are good semiconductors. They have characteristics of both metals and nonmetals. They also have ranging reactivity levels.
Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.

The most reactive nonmetals are located in top most right section of the Periodic Table, excluding group 18 (has no reactivity).
they go from smaller to the largest

The periodicity of nonmetals is that reactivity increases from left to right across a period, through group 17, the halogens. As you move down a group, reactivity decreases. Fluorine is the most reactive element.
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
The Halogens are the most reactive non-metals. However, their reactivity decreases as you go down the group. Most reactive Fluorine>Chlorine>Bromine>Iodine>Astatine Least reactive. However, Astatine is not fully characterised because it is radio-active, and consequently is not found in open(school) labs.

golds reactivity is very low in the reactivity series ....
Is the reactivity of an alloy very different from the reactivity of its major component?"
Americium is a reactive metal and can react with the majority of other nonmetals; also react with inorganic acids or water vapors.The Pauling electronegativity (a measure of reactivity) of americium is 1,5.
