Some reactive metals avoid complete corrosion by the formation of a stable oxide on their surface. Oxygen oxidizes the metal on the surface of the metal, forming a metal oxide. In some cases, this oxide does not easily separate from the rest of the metal, and is inert under the conditions present. In this case, the rest of the metal avoids corrosion, as oxygen cannot penetrate through the oxide layer to react further.

What reactive metals will produce a spark when they are struck?
Reactive Metals
How many reactive metals are there?
All metals are reactive, and there are 91 different metals on the periodic table.
Are gold and platinum reactive metals?
Gold and platinum are less reactive metals but not absolutely non-reactive.
Is most metals reactive.?
It is not true; some metals are not so reactive and noble metals are practically unreactive.
What groups are the very reactive elements from?
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
Where in the reactivity series are the metals most affected by corrosion?
The rate of corrosion is directly linked to a metal's reactivity. The higher the metal in the series, the more reactive, also more susceptible to corrosion with oxygen and water. aluminum is not easy to corrode. Aluminum quickly reacts with oxygen in the air, and the oxide layer that forms protects the metal underneath from any further reaction.
What are the effects of acid on metals?
The main effect would be corrosion, which weakens more reactive metals such as iron much faster than less reactive metals such as gold.

Metals from which groups might be used to provide a protective coating?
Metals from groups 13-15 could be used. The metals in these mixed groups are not very reactive, and so could provide protection against corrosion.
What reactive metals will produce a spark when they are struck?
Reactive Metals

What are the ranks of the periodic table families from most to least reactive?
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Which group of metals is more reactive the alkali metals or the alkaline earth metals?
The alkali metals are more reactive.
How many reactive metals are there?
All metals are reactive, and there are 91 different metals on the periodic table.
Why does corrosion cause loss to national economy?
Corrosion of metals causes great economic loss. It's estimated that 'bout 15% of the total world production of iron is destroyed by corrosion .This corrosion causes a very serious loss 2 national economy .
Why shouldn't dilute acid be added to the most reactive metals?
Dilute acid should not be added to reactive metals because the result is dangerous. This violent reaction can easily cause damage to property or cause harm to people.
What family in the Periodic table contain the most reactive metals?
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
