Answer:
in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
If it has a positive charge it is a cation if negative it is an anion .
I attached a chart that will help you know the charges of the elements
Answer:
The balanced equation for the dissociation of KI is
KI → K⁺ + I⁻
Explanation:
KI is the potassium iodide.
K⁺ comes from the KOH, a strong base, so the cation is the conjugate weak acid and in water it does not react.
I⁻ comes from HI, a strong acid, so the anion is the conjugate weak base and in water it does not react.
K⁻ + H₂O ← KOH + H⁺
I⁻ + H₂O ← HI + OH⁻
That's why the arrow in the reaction is in the opposite direction.
