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
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.
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.
How can you tell if a metal is ferrous or non-ferrous?
Ferrous contains Iron, but non ferrous does not contain any iron
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 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.
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.
