Is bismuth a non metal metal or metalloid?
bismuth is ametal as it shows all the properties of ametal. having high m.p,b.p etc However, a simple way to tell is to check your periodic table as Bismuth is underneath the stair case formed by the metalloids in between the metals and non metals. The metalloids are: Boron, Silicon, Germanium, Arsenic, Antimony and Tellrium. anything to the right of these elements are non metals while anything to the left of these are metals, including Bismuth.
How do you identify if a substance is metal matalloid or non metal?
In simple terms just by looking at them, and doing an electrical conductivity test you can tell the following. the metals are shiny and conduct electricity. The non-metals which are gases or liquids are easy to distinguish. The solid non metals such as sulfur are not shiny and do not conduct electricity. (graphite conducts electricity but is soft and not that shiny). The metalloids look a bit like metals but are very poor conductors of electricity.
Why is the reactivity series important when extracting metals from ores?
By knowing the reactivity series of elements, we can tell which elements will displace each other. So to extract a metal from an ore, you need to use an element higher up in the reactivity series, so that the metal will be replaced by the other element, and you are left with a more pure form of the metal.
What compound forms when metals react with nonmetals?
I think what you are asking is what type of bond is formed, as there are no 'catch all' terms for compounds made from non-metals. Non-metals bond to each other covalently - with a covalent bond. That's the one where electrons are shared, not donated.
What does a roman numeral tell you about transition metals?
formula?
How does the activity series of metals tell which reactions will occur?
Metals higher in the series will replace metal ions in solution that are lower in the series
How can you tell if something is metal?
Properties of metals:- They are malleble, they are shiney, they are ductile and have to be a good conductor of heat and electricity
How can you tell a piece of metal is very old?
Most older metals will be somewhat dull from wear or corrosion- but new metals can be aged to make them look older.
What are 3 metals and tell the name of an ore that contains that metal?
Tin: cassiterite Mercury: cinnabar Uranium: pitchblende
How to tell if a bond is ionic or covalent?
if you have a metal and non metal bonding it's an ionic bond and if it's two non metals it would be a covalent bond.
Is cobalt oxide a metal or nonmetal?
CO is a compound made up of two nonmetals. Not to be confused with Co, which is a metal.
Is bismuth a non metal metal or metalloid?
bismuth is ametal as it shows all the properties of ametal. having high m.p,b.p etc However, a simple way to tell is to check your periodic table as Bismuth is underneath the stair case formed by the metalloids in between the metals and non metals. The metalloids are: Boron, Silicon, Germanium, Arsenic, Antimony and Tellrium. anything to the right of these elements are non metals while anything to the left of these are metals, including Bismuth.
Can you have an MRI if you have metals in your body?
The attendant will ask about what you have in your body--piercings, hip replacements, medicine patches with metal backing--and then will tell you what you have to do. They do not want the metal to shift during the scan.
How do Metal detectors discriminate metals?
Metal detectors work by emitting electromagnetic signals outward. When those electromagnetic signals bounce back to the receiver, the machine knows that there is an object in that location and alerts the user.
How can you tell that ionic bonding will placebetween metals and non metals?
Most of the time the bond between a metal and a nonmetal is ionic. However, there are some exceptions, such as BeCl2, which is covalent. The difference in electronegativity determines what kind of bond will form. Metals and nonmetals with a difference in electronegativity of >1.6 are considered to have an ionic bond.
How do you know if one metal is reacting faster than the other one?
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.
If you look at a compound how can you tell if its a covalent or an ionic bond?
You would need to know the chemical makeup of the compound. Ionic bonding occurs between a metal and a non-metal while covalent bonding occurs between non-metals
