Why are metals that have a high reactivity more expensive to react?

Because in nature they will have most likely to have reacted already.
Also they probably be harder to 'unreact'.

Which metal doesn 't react with HNO3?
Gold and platinum will no react with HNO3 due to their low reactivity. Aluminum also will not react with HNO3 despite its relatively high reactivity because it has a protective layer of aluminum oxide on it.
If copper would have been high up in reactivity series would it still have been a useful metal give reason?
No it wouldn't be. Metals high up in the reactivity series, such as the alkali metals, react with water. Copper metal wouldn't stay a metal for long if it reacted vigorously with water (which is the same reason that lithium, potassium, and sodium and not commonly found in their metallic state). Most metals that react with water are found as dissolved ions, and not as solid metals.See the Related Questions to the left for more information about the reactivity series.
Why are group 1 metals dull on the outside but shiny on the inside?
because of high alkalinity and reactivity, these metals react with oxygen (or other gases) and form a dull layer over them. The inner part remaining protected against gases look shiny, but after sometime they also become dull.
Why do chemists use compounds instead of group 1 and 7 elements?
It is because the group 1 and 7 elements have a high reactivity. The reactivity is far too high to use on there own because the elements in these groups react with air and/or water.
Why hydrogen is liberated when magnesium react with dilute nitric acid unlike other metals where hydrogen is not evolved?
This may due to Magnesium metal has high reactivity and concentration of nitric acid is dilute, thus magnesium reacts with H+ in water/ in nitric acid to give hydrogen
What can you tell about an atom that has high electronegativity?
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
What is electronegravity?
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
What are examples of high reactivity?
Very reactive elements are alkali metals and halogens.
Which metal doesn 't react with HNO3?
Gold and platinum will no react with HNO3 due to their low reactivity. Aluminum also will not react with HNO3 despite its relatively high reactivity because it has a protective layer of aluminum oxide on it.
Which rule for the reaction of a metal with oxides of other metals?
Metals placed high in the reactivity series will reduce the oxides of those lower in the series.

Are alkaline earth metals found in nature?
Alkaline earth metals are found in nature only in mineral or compound forms, due to their high reactivity.
What happens When metals react with other elements the atoms of the metal?
it basiclly has sex and gets high
What can you tell about an atom that has a high electro negativity?
It is more likely to attract electrons. :)
