Answer: The key difference between dissociation and solvation is that dissociation is the breakdown of a substance into the atoms or ions from which the substance is made of whereas solvation is the dissolution of a substance in a solvent due to the attraction forces between the solvent molecules.
The transfer of electrons forms strong bonds between ions I’m pretty sure
Chromium (VI) has a 6+ charge (we can tell that from the number 6 after it) and you should know that Oxygen has a 2- charge (because it needs 2 more electrons to get a full outer shell).
To work out the formula we need to balance the positive and negative charges.
So we have 6+ and 2-...
We need to make 6- so therefore we times the amount of Oxygen by 3.
This makes the formula CrO3.
Hope this is helpful, message me if you have any questions :)
1).C-by analyzing its interactions with another particle
2).C-18
3).C-energy sub-level
Extra stability for an atom means to gain electrons to become stable .example:Cl it has 17 electrons by gaining 1 electron it achieve 18 electrons means it has octet configuration in it valency shell.Now it is stable
