Why does K⁺ have 0 valence electrons? - Chemistry Stack Exchange
Sep 29, 2014 · K+ is isoelectronic with Cl- and Ar, but due to the positive charge it is literally impossible to get K+ to share or give up its 3s electrons (except in the plasma phase), so they …

Aug 19, 2018 · Think of it this way: 1) Count the electrons (all of them) in each atom or ion. 2) What happens to the orbitals, and thus to atoms or ions with a given number of electrons (let …
How to tell which species has the highest ionization energy?
I am preparing for my final exam, and I am very confused about ionization energy. An example question would be: Between the species $\ce {Ne, Na+, Mg^2+, Ar, K+, $\&$~Ca^2+}$, which …
Ionic radius of Al[3+] compared to K[+], Ca[2+], S[2-], and Cl[-]
Apr 27, 2017 · I came across this question: Which of the following is bigger? $$\\ce{K+, Ca^2+, Al^3+, S^2-, Cl-}$$ Now, I know that the radius decreases as the period progresses to the …
If concentration of K+ ions inside the cell is almost equal to ...
I'm a bit confused about electrochemical gradients of sodium and potassium ions. They have similar concentrations and are kind of similar ions but their distribution is different across the …

Feb 19, 2022 · 0 Among $\ce {H+, Li+, K+, Rb+, Cs+}$ in an aqueous medium at infinite dilution at 25 °C, which ions have more ionic molar conductivities than that of $\ce {Na+}$? I know that …
Radius of Ag+ and K+ - Chemistry Stack Exchange
Oct 31, 2023 · According to the database of ionic radius Database of ionic radius The ionic radius of silver(I) cation is totally smaller than potassium(I), regardless of their coordination number. It …
Why is the aqueous solution of KMnO4 slightly basic?
May 9, 2021 · The strength of permanganic acid that you quote, combined with that of potassium hydroxide as a base, would guarantee that pure potassium permanganate is neutral in …
Why is OH- so electrically conductive? - Chemistry Stack Exchange
Jan 10, 2025 · BTW. Be aware that "naked" H+ is just a proton and free protons immediately bind themselves to electron pairs of water molecules. Better is to write H+ (aq), with much higher …
Why does potassium react the most vigorously with water?
This means that when KOH K O H dissolves in water it'll form the K+ K + electrolyte, which is not the same thing as a pure K K atom with its 19th electron. A K K atom, then, since it's the most …
