Which element has a higher melting point potassium in group 1A for calcium in group 1B?
Calcium, which is in Group 2 (not 1B, as there is no Group 1B), has a higher melting point than potassium, which is in Group 1. This is due to calcium being a metal with a higher atomic number and stronger metallic bonds compared to potassium, resulting in a higher melting point. Calcium's melting point is approximately 842°C, while potassium's is around 63.5°C.
Which would you expect to have a higher melting point sodium chloride NaCI or aluminum oxide AI203?
The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.
Why aluminium has a higher melting point than sodium?
Aluminium has a higher melting point than sodium primarily due to its metallic bonding structure. In aluminium, atoms are held together by strong metallic bonds involving a greater number of delocalized electrons, resulting in a more stable and tightly bonded lattice structure. In contrast, sodium has a simpler metallic structure with weaker metallic bonds, leading to a lower melting point. Additionally, the higher atomic mass of aluminium contributes to its stronger bonding interactions.
What is the meting point for potassium?
The melting point for potassium is 63.38 °C.
What is the boligng point and melting point of potassium?
Boiling point 774°C Melting point 63.65°C
Does rubidium have a higher melting point than potassium?
Yes, rubidium has a higher melting point than potassium. Rubidium has a melting point of 39.3°C, while potassium has a melting point of 63.4°C.
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.
Which element has a higher melting point potassium or calcium?
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
Which element has a higher melting point potassium in group 1A for calcium in group 1B?

Calcium's melting point is approximately 842°C, while potassium's is around 63.5°C.
Which of properties does lithium have a larger value than potassium?
The potassium is larger radius because it has more electron shells.
Which would you expect to have a higher melting point sodium chloride NaCI or aluminum oxide AI203?
The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.
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.
Why aluminium has a higher melting point than sodium?
Aluminium has a higher melting point than sodium primarily due to its metallic bonding structure. In aluminium, atoms are held together by strong metallic bonds involving a greater number of delocalized electrons, resulting in a more stable and tightly bonded lattice structure. In contrast, sodium has a simpler metallic structure with weaker metallic bonds, leading to a lower melting point.

Boiling and melting point of aluminium?
The boiling point of aluminium is 2467°C (4473°F) and the melting point is 660.3°C (1220.5°F).
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 bromide?
The melting point of potassium bromide is 734 degrees Celsius.
What is the meting point for potassium?
The melting point for potassium is 63.38 °C.
