Chemical formula of potassium bromide is KBr. Potassium and bromide ions make a giant lattice. It is very hard.

Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Which is softest sodium or lithium?
sodium is a softer metal than lithium.
Why is potassium salt better for you than sodium salt?
Potassium salt is not better; it is recommended for some diets without sodium.
What is the atomic letter for sodium and potassium?
Sodium - Na Potassium - K
What substances are transported by active transport?
Sodium Potassium
Is rubidium harder or softer than potassium why?
it is softer
Sodium is preferred over potassium in industrial applications because why?
$$$$$$ Sodium is cheaper!!!!$$$$$$ They both work great for the same purposes and are very often interchangeable. (But potassium hydroxide makes much softer and, to me, more pleasant feeling soap than sodium hydroxide)
Is potassium more or less active than sodium?
Potassium is more reactive than sodium
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Which is softest sodium or lithium?
sodium is a softer metal than lithium.
Which is the stronger base what Sodium Hydroxide or Potassium Hydroxide?
Potassium Hydroxide is stronger than sodium hydroxide
Which is more reactive than sodium?
Potassium
Why is potassium salt better for you than sodium salt?
Potassium salt is not better; it is recommended for some diets without sodium.
Is francium harder or softer than sodium?
The hardness of francium is not known.
Is diclofenac potassium is more powerful than diclofenac sodium?
Case to case basis. In my case diclofenac potassium is more powerful than diclofenac sodium.
Why sodium is more reactive than potassium?
The atomic radius of potassium is greater than that of sodium. Therefore, the single valence electron that exists for all alkali metals is located farther from the nucleus for potassium than sodium. This results in less energy required to remove that valence electron from potassium than from sodium, leading to increased reactivity. Note that this trend continues as you move down Group I on the Periodic Table, meaning that Rubidium is more reactive than Potassium and Cesium is more reactive than Rubidium.
Why is sodium preferred over potassium in industrial applications?
The question isn't very specific (preferred for what?!), but sodium metal is less reactive than potassium. It is also slightly more abundant than potassium on Earth.
