∙ 13y agoYes, all the metals are reactive but the differences in reactivity are very important.

Also oxygen and hydrogen are reactive.

What happens to the reactivity nonmetals as you move down a period?
The reactivity is increasing, from left to right - for example halogens.
Do Nonmetals with lower electron affinity have higher reactivity?
No. The most reactive non metal, fluorine, has the highest electron affinity.
What are the characteristics of semi metal?
Semi-metals (or metalloids) are good semiconductors. They have characteristics of both metals and nonmetals. They also have ranging reactivity levels.
What happens to non metals across the periodic table?
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.
When nonmetals react with other nonmetals the atoms of nonmetals do what with electrons?

Where are the most reactive nonmetals located on the periodic table?
The most reactive nonmetals are located in top most right section of the Periodic Table, excluding group 18 (has no reactivity).
What happens to reactivity of nonmetals within a group from the top of the group to the bottom?
they go from smaller to the largest

How do you tell the reactiveness of a non metal on the periodic table?
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.
What is reactivity of properties of metals?
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
Are the halogens most reactive nonmetals or the least reactive 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.

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.
What is gold's reactivity?
golds reactivity is very low in the reactivity series ....
Is the reactivity of an alloy very different from the reactivity of its major component?
Is the reactivity of an alloy very different from the reactivity of its major component?"
What is the reactivity of americium?
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.
