What does a roman numeral tell you about transition metals?
Roman numerals in transition metal names indicate the oxidation state of the metal ion. This is important because transition metals can exist in multiple oxidation states, so the Roman numeral helps to specify which one is present in the compound.
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.
What is the three main groups of metal materials?
The three main groups of metal materials are ferrous metals (containing iron), non-ferrous metals (not containing iron), and noble metals (resistant to corrosion and oxidation). Ferrous metals include steel and cast iron, while non-ferrous metals include aluminum, copper, and lead. Noble metals consist of gold, silver, and platinum.
Things that are made of metal?
Some things made of metal include cars, cutlery, and appliances. Metals are also commonly used in construction for buildings, bridges, and machinery. Additionally, jewelry and coins are often made of precious metals like gold and silver.
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.
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 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.
How can you tell if something is metal?
You can tell if something is metal by checking if it is shiny, conducts electricity, and is malleable and ductile. Metals also tend to be heavy and have a high melting and boiling point compared to other materials.
What are 3 metals and tell the name of an ore that contains that metal?
Tin: cassiterite Mercury: cinnabar Uranium: pitchblende
How do you tell if an element is a metal with a hammer?
You can tell if an element is metal with a hammer by determining if it is malleable (meaning that it can be molded or bent). Just smash it with the hammer, and if it shatters, it probably isn't a metal.
How can you tell if a metal is ferrous or non-ferrous?
One way to tell if a metal is ferrous or non-ferrous is by using a magnet. Ferrous metals are magnetic, meaning they are attracted to magnets, while non-ferrous metals are not. Additionally, you can also consult a materials data sheet or perform a chemical test to determine the composition of the metal.

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.
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.

If x stands for a metal how can you tell from the following formulas xcl and xcl2 which compound contains an alkali metal and which contains an alkaline earth metal?
You have to balance the valence between the metal and Cl. Cl wants one electron, so it has a charge of -1. It takes one alkali metal to balance that charge, since alkali metals only give up one electron. This means XCl is made of an alkali metal. Alkaline earth metals give up two electrons, and so it can give one of those two electrons to two Cl. Therefore, XCl2 contains an alkaline earth metal
