Cesium Chloride Density Gradient Centrifugation and Isotopes
In Cesium Chloride Density Gradient Centrifugation, as used by Meselson and Stahl, Cesium ions can be seen as strongly affected by centrifugation, so much so that they can overcome their ionic bonds ...

Ionic bond formation [duplicate]
When two separate pieces of sodium chloride crystals are physically put together, no wonder that they will not fuse with each other.
But I don’t understand why. Ionic bonds are described to be non-...

Why is the statement regarding the strength of ionic bonds reasonable? [closed]
In largely ionic compounds (e.g. NaBr and NaI), it seems to be generally true that, the greater the differences of electronegativity between the forming substances (i.e. The compound has more "...

Calculating salinity from sodium and chloride in water [closed]
let me start by saying that I am definitely no chemist, so this question might (or might not) seem trivial to all you professionals out there.
I have recently found a brand of carbonated water here in ...

why chemical bond between Na and Cl happens [closed]
We know that if Cl and Na get too close, they produce ionic bonding.
Cl has 17 proton and 17 electrons and is considered stable.
Na has 11 protons and 11 electrons and is considered stable.
I ...

Can ionic and/or metallic bonding produce stable long chains? Like polymers, though not necessarily as useful [closed]
Question
Polymers are long chains ��️ of covalent bonds.
Can similar structures exist for ionic and/or metallic bonding? They don't have to be as useful.
I know there can be polymers with ionic bonds ...

Confusion related to exception in Fajan's rule (Regarding prediction in solubility of compounds in polar solvents)
My teacher taught us that higher the ionic character in a compound, higher is its solubility in polar solvents like water.
To illustrate this statement, he also gave us the following example-
LiOH< ...

AlCl3, Al2O3, Al(OH)3. What is more ionic?
I tried with fajans' rules.
First I got AlCl3 and Al2O3. There, because O2- has high negative charge I decided that Al2O3 is less ionic. But my teacher told us that we can get the same thing by ...

Why aren't ionic crystals stronger than diamond?
If ionic bonds are stronger than covalent bonds, then why aren't ionic crystals stronger than diamond, which is bonded by covalent bonds?
Diamond has tetrahedral structure with carbons forming ...

What are the Ionic Properties of Co-ordinate Covalent Bonds? [closed]
In my 10th grade book, it says that
A coordinate bond has properties of both covalent and ionic bonds. Therefore, it is also called dative or co-ionic bonds.
I understand that it has properties of ...

If bond types are in reality intermixed, how come different bonds form completely different structures?
According to the bond triangle, compounds don't exist as solely ionic or solely covalent, but rather have ionic, covalent, and metallic character to them. So each bond type is connected and similar in ...

Why is the thermal stability of calcium carbonate higher than that of magnesium carbonate even though lattice energy decreases down a group?
The difference in thermal stability of $\ce{CaCO3}$ and $\ce{MgCO3}$ can be explained using Fajans' rules, but why not using the lattice energy method?
Why is the thermal stability of $\ce{CaCO3}$ ...

Ionic compounds with hydride anion [closed]
Ionic compounds are formed when an atom $\ce{A}$ donates one of it's electron to another atom $\ce{B}$ to form an ionic compound $\ce{A+B-}$. This is significantly more likely to happen as the ...

Determining whether a compound is ionic or molecular in nature [closed]
$\ce{HCl}$ is a molecular compound because there is a covalent bond between $\ce{H+}$(a proton) and $\ce{Cl-}$ (a chloride ion)
$\ce{NH4NO3}$ is an ionic compound because there is an ionic bond ...
