What is the oxidation number of mercury in amalgums?
In amalgams, the oxidation number of mercury is typically 0 because it is in its elemental form. Amalgams are alloys of mercury with other metals, where the mercury atoms do not change their oxidation state.
What is a alloy made with mercury?
One example of an alloy made with mercury is dental amalgam, which is a mixture of silver, tin, copper, and mercury used in dental fillings. Mercury forms a strong bond with the other metals, creating a durable and long-lasting material for dental applications.
What is the difference between high copper and low copper amalgam?
Briefly explained, low copper amalgams are also known as "traditional" or "conventional" and have been used for many decades (even at present) and contain less than 6 % copper, while high copper amalgams contain more than 6 % copper, in fact there are 2 main groups, one containing around 12-13 % copper, and the other containing up to 30 % copper. The additional copper helps to increase the formation of gamma 1 (silver-tin) and prevent the formation of a weak phase of dental amalgams, named gamma-2 (tin-mercury) and thus the strength of the final product is higher. Therefore, the high copper amalgams have a higher compressive strength and in general, better mechanical properties, but there is one disadvantage, they release more mercury vapor, a poison for the brain, CNS and many other cells.
What is the alloy of mercury and silver called?
The alloy of mercury and silver is called an amalgam. Amalgams are commonly used in dentistry for dental fillings due to their strength and durability.
What is the solvent in amalgam?
The solvent in dental amalgam is mercury. Mercury is used to bind together the powdered metals in dental amalgam to form a strong and durable filling material.
What kind of metals are in amalgams?

Is an amalgrams a solution?
Amalgams are solid alloys of mercury, mixtures.
Are dental amalgams poisonous?
No, in general it is not poisonous, else it were to be forbidden.
Are amalgam tattoos contagious?
Nope! They are like a normal tattoo - confined to one area, they cannot spread by themselves. However, multiple amalgams may result in a person having more than one. New ones may appear if old amalgams are replaced, new amalgams are placed or if a tooth with an amalgam is extracted.
What has the author William Cabler Moore written?
William Cabler Moore has written: 'Organic amalgams: substances with metallic properties composed in part of non-metallic elements ..' -- subject(s): Accessible book, Amalgams

I'm 29 yr-old and plan to get pregnant and have 6 amalgams in my mouth.Should I remove amalgam and using other fillings instead. Need your suggestion?
See your dentist, but as long as none of your amalgams are leaking you should have no problems.
