Chemical formula of potassium bromide is KBr. Potassium and bromide ions make a giant lattice. It is very hard.
What else can I help you with?
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?
Lithium is softer than sodium. Sodium is harder because it has a higher atomic number and more electrons, which results in stronger metallic bonding compared to lithium.
What element has a lower ionization energy than Na?
Potassium (K) has a lower ionization energy than sodium (Na).
What is the atomic letter for sodium and potassium?
The atomic symbol for sodium is Na and for potassium it is K.
Are Excitable cells like neurons are more permeable to sodium than to potassium?
Yes, excitable cells like neurons are more permeable to sodium ions than potassium ions. This selective permeability is due to the presence of more sodium channels compared to potassium channels in the cell membrane, allowing sodium to flow into the cell more readily during an action potential.
Is rubidium harder or softer than potassium why?
Rubidium is softer than potassium. This is because rubidium has larger atomic size and higher reactivity, which makes it more easily deformable when compared to potassium.
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Why sodium has more density than potassium?
Sodium has a higher density than potassium because it has a greater atomic mass per atom. This means that sodium atoms are heavier than potassium atoms, leading to a higher density of sodium compared to potassium.
What metals softer and more reactive than other metals?
Potassium, sodium, and lithium are softer and more reactive than other metals. They are typically stored in oil or kerosene to prevent them from reacting with moisture in the air.
What metal can displace sodium?
Potassium can displace sodium, as potassium is more reactive than sodium. When potassium is added to a solution containing sodium ions, a displacement reaction can occur where potassium replaces sodium in the chemical compound.
Which is softest sodium or lithium?
Lithium is softer than sodium. Sodium is harder because it has a higher atomic number and more electrons, which results in stronger metallic bonding compared to lithium.
Is iron softer than potassium?
No, iron is harder than potassium. Iron is a metal with a higher Mohs hardness rating than potassium, which is a soft alkali metal.
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)
Which is the stronger base what Sodium Hydroxide or Potassium Hydroxide?
Sodium hydroxide is a stronger base than potassium hydroxide. This is because sodium hydroxide has a higher dissociation constant and a higher solubility than potassium hydroxide, making it more effective at accepting protons.
Does sodium have the larger first ionization energy than potassium?
No, potassium has a larger first ionization energy than sodium. Potassium has an extra electron in its valence shell compared to sodium, making it more difficult to remove an electron from a potassium atom compared to a sodium atom.
Why do potassium salts of fatty acids yield soft soap?
Potassium salts of fatty acids should yield soft soaps because they are more soluble in water than sodium salts of fatty acids (which yield hard soaps). They contain more water, so they are softer.
Why sodium is softer than lithium?
Sodium is softer than lithium because sodium has a larger atomic radius and more electron shells. This allows the electrons to be further from the nucleus, leading to weaker metallic bonds and making sodium easier to deform.
