Can metal kationts be liquid, like Mn+7 in red?

SUMMARY

The discussion clarifies that manganese cation (Mn+7) cannot exist as a pure liquid due to electrostatic repulsion between similarly charged ions. Instead, the red liquid observed is a solution of manganese heptoxide (Mn2O7) dissolved in water, where Mn+7 is a component of the compound rather than a standalone liquid. The confusion arose from the labeling of Mn+7, which is often misinterpreted as a liquid state.

PREREQUISITES
  • Understanding of cations and their properties
  • Knowledge of chemical compounds and their states
  • Familiarity with manganese chemistry
  • Basic principles of electrostatics in chemistry
NEXT STEPS
  • Research the properties of manganese heptoxide (Mn2O7) and its behavior in solution
  • Study the principles of ionic compounds and their solubility in water
  • Learn about the electrostatic forces between charged ions
  • Explore the chemistry of transition metals and their oxidation states
USEFUL FOR

Chemistry students, educators, and professionals interested in transition metal chemistry and ionic compounds.

Hi all,

I have a small question. I have checked it: http://neon.chem.ox.ac.uk/vrchemistry/LiveChem/transitionmetals_content.html

and I am very confusing. There is some kationts of metal and these are liquid !
For example mangan kationt : Mn+7 is red liquid. Is it possible ?

PS:I am sorry for my englisch, its not good !

I think you are referring to cations. The ions you are looking at are actually compounds that are dissolved in water. The Mn + 7 comes from a salt (i.e. Mn(2)O(7)) being dissolved in water. The Mn+7 is what give it the charactersitic red color, but there is a counterion also in the liquid. It is not possible to have a liquid of only Mn+7 as the charge of each ion would repel each other ion.
 
thanks

Thank you for your answer.
I was only confused about label Mn+7.
