Metals, Less Reactive

Add to MyChemicals

There are 43 chemical datasheets assigned to this reactive group.

What are reactive groups?

Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure. Each substance with a chemical datasheet has been assigned to one or more reactive groups, and CAMEO Chemicals uses the reactive group assignments to make its reactivity predictions. More info about reactivity predictions...

If you can't find a chemical in the database--but you know what reactive group it belongs in--you can add the reactive group to MyChemicals instead in order to see the reactivity predictions.

Flammability
Nonflammable. Not reactive enough to burn in air, even if finely divided.
Reactivity
Metals in this group can react exothermically with oxidizing acids to form noxious gases. Many catalyze polymerization and other reactions, particularly when finely divided. Metals in this group have been known to react with halogenated hydrocarbons, sometimes forming explosive compounds (for example, copper dissolves when heated in carbon tetrachloride). They are less reactive in massive form (sheet, rod, or drop) than when finely divided.
Toxicity
Fumes from the hot metals are toxic by inhalation.
Other Characteristics
This reactive group includes items (such as certain munitions) that employ less reactive metals or their alloys for housings, supports, tanks, and other structural purposes.

Also included are metals that do not react with air, such as the platinum group metals (platinum, palladium, rhodium, iridium, ruthenium, and osmium), and the coinage metals (copper, silver, and gold). These metals are resistant to corrosion, so they are often used for coinage and jewelry, and they are excellent conductors of electricity, so they are ideal for use in electrical components. Although these metals tend to be unreactive in most situations, they are also known as catalytic metals, especially if finely divided.
Examples
Copper, lead, mercury, silver, gold, palladium, platinum.

The predicted hazards and gas byproducts for each reactive group pair will be displayed, as well as documentation and references that were used to make the reactivity predictions.
