What is the melting and boiling points of helium in dgrees C?
The melting point of helium is 1.15 K and its boiling point is 4.22 K. So in oC they would be: Melting Point: 1.15 - 273.15 = -272.00 oC Boiling Point: 4.22 - 273.15 - 268.93 oC
Which has the greatest number of atoms- 3.5 grams of helium or 3.5 grams of lithium?
3.5 grams of lithium would have a greater number of atoms because lithium is heavier than helium. Each element has a different atomic mass, so the same weight of each element will contain a different number of atoms.
What is the melting point for helium in kelvin?
helium is a gas so it doesnt meltThe melting point of Helium is
Which element has a low melting point and boiling point?
The element with the lowest melting and boiling point is helium. Helium is a noble gas with an atomic number of 2 and a very low atomic mass, which contributes to its low melting and boiling points. At standard pressure, helium has a melting point of -272.2 degrees Celsius and a boiling point of -268.9 degrees Celsius.
What is the name of the compound with the formula LiNO3?
Li3N would be lithium nitride. LiNO3 would be lithium nitrate. LiN3 does not exist.
What is the state of lithium at 100 degrees Celsius?
At 100 degrees Celsius, lithium would be in a solid state. Lithium has a melting point of 180.5 degrees Celsius, so at 100 degrees Celsius it would still be a solid.
What is the melting and boiling points of helium in dgrees C?
The melting point of helium is 1.15 K and its boiling point is 4.22 K. So in oC they would be: Melting Point: 1.15 - 273.15 = -272.00 oC Boiling Point: 4.22 - 273.15 - 268.93 oC
Which balloon would fly higher the one with helium or the one with air?
The balloon with helium.
What is the lightest weight element that is not a gas?
The lightest weight element that is not a gas at room temperature is lithium. It is a solid metal with a low density and atomic number 3.
Which has the greatest number of atoms- 3.5 grams of helium or 3.5 grams of lithium?
3.5 grams of lithium would have a greater number of atoms because lithium is heavier than helium. Each element has a different atomic mass, so the same weight of each element will contain a different number of atoms.
What is the Melting point and boiling point in c of helium?
The melting point of helium is 1.15 K and its boiling point is 4.22 K. So in oC they would be: Melting Point: 1.15 - 273.15 = -272.00 oC Boiling Point: 4.22 - 273.15 - 268.93 oC
How come there's no melting point for helium?
There is, it's -272.05°C. Melting point is the same as freezing point, you might have searched for the wrong one, but you would call it freezing in helium because it is gas at room temperature.
What is the melting point for helium in kelvin?
helium is a gas so it doesnt meltThe melting point of Helium is
Do red giant stars have lithium in their cores?
some, but not much. the principle componant of a red giant's core is helium. lithium is not a product of stellar nuclear reactions, so any lithium in a star would have been there from when the gas cloud collapsed into a protostar.
Which element has a low melting point and boiling point?
The element with the lowest melting and boiling point is helium. Helium is a noble gas with an atomic number of 2 and a very low atomic mass, which contributes to its low melting and boiling points. At standard pressure, helium has a melting point of -272.2 degrees Celsius and a boiling point of -268.9 degrees Celsius.
What state is lithium at 100 degrees Celsius?
At 100 degrees Celsius, lithium is a solid. It has a melting point of 180.5 degrees Celsius, so at 100 degrees Celsius, it would still be in solid form.
Which would be least reactive because its last electron shell is full with 2 electrons 1.helium 2.neon 3.lithium 4 bromine?
Helium would be least reactive because its last electron shell is full with 2 electrons, giving it a stable electron configuration. Neon also has a full outer electron shell but belongs to the noble gases group. Helium is a noble gas, hence more stable and less reactive compared to lithium and bromine.
