Why are potassium sodium and lithium stored in a jar of oil and not in an empty jar?
Wiki User
∙ 10y ago
Li, Na, & K are all Group '1' metals.
They all vigorously react with oxygen.
Since oil is a hydrocarbon ( no oxygen present), these metyals remain unreactive.
Jowever if stored in an ordinary jar, they would be in contact with oxygen (air( and so would tarnish.

Why potassium dichromate is orange red in color?
The orange color of potassium dichromate is caused by the movement of an electron to a vacant d-orbital in the manganese atom. The transition occurs when the chemical is in the presence of light. This is confirmed by the empty 3d-orbital in chromium.
Why does potassium form compounds?
potassium- element 19, alkali metals, atomic symbol "K" potassium is rarely if ever found in its pure form, this is because it only has one valence electron, the closer an atom is to a totally full or totally empty valence energy level, the more it wants to bond with an element that will give it a full shell, so in the case of covalent bonds, potassium will bond with an atom that has 7 valence electrons or just something that will give the compound 8 valence electrons hope this helped!
In the compound sodium fluoride NaF the sodium atom loses one electron and the fluorine atom gains one electron to form ions that have electron configurations similar to?
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
Lithium Batteries Have No Memory Effect?
When you buy lithium polymer batteries, you can do so with the knowledge that they do not have the dreaded memory effect. This new technology is much better than the batteries that used to be used in computers, phones, and the like. These batteries would remember how full they were when you plugged them in, and they would count that as being empty, even if they were not. The lithium polymer batteries do not do this.
How many empty spaces are there for electrons on the outer ring of sodium?
This may be trick question.In practise to make up the octet which would give sodium the electronic configutration of Argon, there is ony space for 7.However the electronic confugration of sodium is [Ne]3s1The outer shell, 3, has the following orbitals.3s, three p orbtals 3px, 3py, 3pz AND five d orbitals , and 3dx2, 3dxy, 3dyz, 3dzx, 3dx2-y2 (sorry the sufixes don't come out right- you need to look at a text book)Theoretically then we have space for 18 electrons in the outershell, so sodium could take on 17!
Should oral forms of potassium be given on an empty stomach?
no
Why is the empty vial weighed after pouring the sodium chloride out?
The empty vial is weighed after pouring the sodium chloride out in order to determine the actual amount of product that was produced by the reaction. By taking the full vial and subtracting the empty vial you can calculate the weight of the product.

Do you have to urinate?
Yes, you must urinate. Urine is continuously produced in your kidneys and stored in your bladder, and you must empty your bladder from time to time.
When you delete a file from a hard disk the deleted file is stored in the Recycle Bin where you can recover it until you empty the Recycle Bin true or false?
This is true, after you empty the recycle bin the contents that were in the bin are lost for forever. You can still restore something from the bin before hitting empty to save it.
