### Has a carbon compound ever been found having an ionic bond?

Why unlikely? Ionic compounds of carbon have been known for ages. There are ionic carbides ($\ce{Al4C3}$, $\ce{CaC2}$, etc.), graphite intercalation compounds like $\ce{KC8}$, ionic derivatives of ...

### Can 100% covalent bonds exist?

According to Pauling's famous The Nature of the Chemical Bond , 3rd edition, at page 73: In the hydrogen molecule a quantum-mechanical treatment has shown that the two ionic structures $\ce{H+H-}$ ...

### If I drink water without sipping, is there a chance of saliva diffusing into my bottle?

This question reminds me of a germaphobic classmate I had back in Middle-school. He would always stay clear of public lavatories/urinals because he was under the impression that urinating at one would ...

### Are all NO3- salts soluble in water? If so, why?

No, the correct way of putting it is $$\mathrm{Almost~all~of~the~\mathbf{inorganic}~nitrate~salts~are~soluble~in~water. }$$ The families of organic nitrate salts are typically nitrates of azoles and ...

### Are metallic/ionic bonds weaker than covalent bonds?

Quartz and diamond are stronger substances because their molecules form network covalent structures. These structures form a lattice-like structure, much the same as ionic compounds. This molecular ...

### The impossibility of 100% ionic bond

A "100% ionic" bond would be a bond whose bonding electron(s) were never in the vicinity of the cation, but rather always in unperturbed valence orbitals of the anion. That's not far from the truth ...

### Is KF the most ionic compound?

Yes, this is a subtle thing. Using the Pauling electronegativities, one would expect CsF to have the larger electronegativity difference (3.2). So in principal, it should be "more ionic." ...

### Has a carbon compound ever been found having an ionic bond?

There is also the classical case of the aromatic carbocations and carbanions; examples include tropylium bromide, and sodium cyclopentadienide, which is used for preparing "sandwich compounds", among ...

### What is Sodium Chloride like in gas state?

No, in the gas phase sodium chloride exists as a monomer (the sodium chloride molecule) along with its dimer $\ce{Na2Cl2}$. The dimer has a roughly rectangular shape and is quite floppy with ...

### Is the bond in HF ionic while it is covalent in HCl?

Bonds can be completely covalent as in $\ce{Cl-Cl}$, $\ce{H-H}$, etc. In these cases the electron density is shared equally between the two atoms. Bonds can also be ionic as in $\ce{Na^{+} Cl^{-}}$ ...

### Are all ionic compounds salts?

Interestingly, IUPAC states that a "salt" is "a chemical compound consisting of an assembly of cations and anions". Under this definition, all ionic compounds are salts, and all salts are ionic ...

### Covalent and Ionic Bonds

Bonds are usually used to describe how electrons are shared. "Partially ionic bonds" are polar covalent bonds. Which is not the same as saying that a compound has different types of bonds in the whole ...

### Is calcium chloride an acidic or basic salt?

Calcium hydroxide has solubility about 1.9 g/L. This is enough to create pH above 11, i.e. a strongly basic solution. $\ce{CaCl2}$ solutions should be very slightly acidic if they were made from pure ...
