Coating with a metallic layer (galvanization), varnishing, alloying to obtain more resistant alloys.
It depends on what they are reacting with.
Metals react with air in a form called oxidizing. This is caused because the oxygen molecules are reacting with the surface of the metal.
Non metals form ionic bonds with metals. Non metals gain the electrons while metals loose. Alkali metals reacts with halogen family in efficient manner.
Nonmetals typically react with both metals and other nonmetals. When reacting with metals, nonmetals can gain electrons to form negative ions, as seen in halogens reacting with alkali metals. In reactions with other nonmetals, they may share electrons to form covalent bonds, such as in the formation of molecules like water (H2O) and carbon dioxide (CO2). Additionally, nonmetals can participate in oxidation-reduction reactions, where they may either gain or share electrons.
When metals burn in air they form metal oxides.
Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are the main alkali metals, which all react fairly spectacularly with water (Cesium must be kept in argon gas to stop it reacting with air).
It depends on what they are reacting with.
The alkaline metals react with water, and Lithium and Sodium float on the water whilst reacting.
There is different ways. Either you make an experiment yourself by reacting the different metals with a substance and then stopping the time it took for each reaction to stop ( quicker = more reactive) Or you can use already done experiments and look for your metal in there. Also there are columns of reactivity for metals. These tell you which metals are more reactive. The more reactive ones are the ones that are going to react faster. THis can be essential when choosing the right metal for a reaction.
Physical properties of metals include: luster, malleability, and ductility. Chemical properties include: forming cations, and reacting with nonmetals to form ionic compounds.
Not all metals react with water, but some, such as metallic sodium, do react quite vigorously with water. In a sense it is true that when metals react with water it is the same as reacting with oxygen, because the water molecule (H2O) does contain oxygen, and it is the oxygen in the water molecule with which metals react. Metals do not react with the hydrogen content of the water molecule, so when metal reacts with water, hydrogen gas is produced as a byproduct. It just bubbles out of the water.
oxygen? i think
Halogens: When reacting with halogens, these metals create metal halides. Halide refers to a compound that is one part halogen. These reactions would look similar to
It contains an acidic sequestring agent corrosively reacting with metals. (citric acid)
The alkali metals, such as sodium, potassium, and lithium, are known for reacting violently with water. When these metals come into contact with water, they produce hydrogen gas and can create a vigorous reaction, sometimes even resulting in sparks or flames.
Metals react with air in a form called oxidizing. This is caused because the oxygen molecules are reacting with the surface of the metal.
Potassium, sodium, and lithium are softer and more reactive than other metals. They are typically stored in oil or kerosene to prevent them from reacting with moisture in the air.
