How could you use a precipitation reaction to separate two metal ions from each other?
You can use a precipitation reaction to separate two metal ions by taking advantage of their different solubilities. By adding a reactant that forms an insoluble precipitate with one of the metal ions, it will selectively remove that metal ion from the solution, leaving behind the other metal ion. The precipitate can then be filtered out and the remaining solution can be further processed or tested for the presence of the other metal ion.
When rubidium reacts with oxygen to form an ionic compound how many ions does each metal lose?
Two ions are lost.
Why do group 2A metals form ions with a positive 2 charge?
These metal may lose two electrons.
How many colors of blood are there and what are the causes for their color?
There are two well known types of "blood colors". The color of the blood is closely related to the oxygen molecules. O2 molecules can be bound in different ways: by the ferrous heme groups of the globins (e.g., myoglobin and hemoglobin); or by two Cu+ ions held in close proximity by six His side chains in hemocyanins. Fe2+ and Cu+ ions and ferrous heme groups free in solution do not bind reversibly; instead, they oxidized to the Fe3+ and Cu2+ forms. Under these circumstances, when Fe2+ is oxidized to Fe3+ acquires a red color, this is the reason why blood is red in upper organisms, those that have hemoglobin. On the other hand, when Cu+ oxidizes to Cu2+ turns to blueish color. In lower organisms (e.g., crustacea) the blood turns blueish when is exposed to oxygen. In resume, we have two blood colors, red and blueish, when it's oxidized.
There are two elements in the transition metal series rm Sc through rm Zn that have four unpaired electrons in their 2 plus ions?
Cr and Fe have four unpaired electrons in their 2 plus ions.

Which of the following describes what takes place when iron (Fe) is oxidized to Fe2 ions?
Iron loss two electrons.
How many metal atoms are in NaF?
none its two ions one of which (Na) comes from a metal
What involves the attraction of two oppositely charged ions?
In Ionic bonding, a metal and non - metal become ions and attract each other. The metal will lose an electron and become positively charged and the non-metal will gain an electron and become negatively charged. As opposite charges attract they form an ionic compound.
What kind of bond will two fluoride ions create?
Ionic bonds are between metal and non-metal. Covalent bonds are between non-metals. Two Flouride ions would both be non-metals.
When rubidium reacts with oxygen to form an ionic compound how many ions does each metal lose?
Two ions are lost.
Can two non metal atoms exchange an electron to form ions?
yes.
Can two non-metal atoms exchange an electron to form ions?
yes it can. yes it can.
When atoms loses electrons to another and the two resulting particles are attracted to each other because they are oppositely charged but without sharing electrons?
This mostly occurs between a metal and non-metal atom where the non-metal gains electrons from the metal. The two ions produced have an equal and oposite charge and so are attracted to each other forming an ionic bond.
What two things react with lithium?
Lithium is a highly reactive metal, so it can react with many other ions, especially halogens such as fluorine, chlorine, bromine, and iodine
What kind of metal is copper?
Copper is an element made up of copper atoms.
How many ions are there in aluminium chloride?
There are two ions, aluminum is one ion and chloride is the other ion
