Which element has a higher melting point potassium or calcium?
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
Why the melting point of potassium fluoride is higher than the melting point of potassium iodide?
KF has small size than KCl. So the packing of atoms / ions in KF is more than that in KCl. So a larger energy is needed to separate the atoms from solid state to liquid state and hence KF has higher melting point than KCl.
What is the melting point of potassium iodide?
The melting point of potassium iodide is approximately 681 degrees Celsius.
What is the melting point of KI?
The melting point of potassium iodide (KI) is 681 degrees Celsius (1,258 degrees Fahrenheit).
What element has the highest melting point out of lithium or magnesium?
Magnesium has a higher melting point.
Is the melting point of sodium higher or lower than rubidium?
Sodium has a melting point of 97.72 oC and rubidium has a melting point of 39.48 oC.
Does sodium have a higher melting point then potassium?
Yes, sodium has a higher melting point than potassium. Sodium has a melting point of 97.8°C while potassium's melting point is much lower at 63.38°C.
What is Rubidium's melting point in celsius?
Rubidium's melting point in celsius is 39.48 degrees.
Which element has a higher melting point potassium or calcium?
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
What element which melting point is 40 degees?
The melting point of rubidium is: 39,31 0C.
Which of properties does lithium have a larger value than potassium?
The potassium is larger radius because it has more electron shells.
Why boiling point of potassium higher than its melting point?
The boiling point of an element is often higher than its melting point because it takes more energy to separate the molecules in a liquid and turn them into a gas. In the case of potassium, the boiling point is higher than the melting point because the forces holding the potassium atoms together in a liquid state are stronger than in a solid state.

What is the meting point for potassium?
The melting point for potassium is 63.38 °C.
What is the melting point of potassium bromide?
The melting point of potassium bromide is 734 degrees Celsius.
Is Rubidium a liquid solid or a gas?
Rubidium is a solid at room temperature and pressure. It has a melting point of 39.3°C (102.7°F) and a boiling point of 688°C (1270°F), so it can exist in liquid and gaseous forms at higher temperatures.
Is rubidium soft or hard?
Rubidium is a soft metal. It has a low melting point and can be easily cut with a knife.
