how do you figure out which has the highest melting point
Therefore, B will have a higher boiling point and melting point than C. Molecule A is ionic (it has charges). Therefore, it can form the strongest ion-ion interactions and will have the highest boiling point and melting point.... Lighter elements such as hydrogen and helium tend to have very low boiling points, and elements with greater atomic mass boil at higher temperatures. The atomic mass affects the forces between atoms, which in turn determine boiling points.
Cobalt Element information properties and uses
Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point. Answer: F2, Cl2, Br2, I2 Which substance has the highest/lowest melting/boiling point, etc. SURPASS TUTORS. 3. Which has the higher vapour pressure, C20H42 or C30H62? Answer Higher vapour pressures correspond to weaker intermolecular forces. Go through the list above. 1. None of these have... The melting and boiling point of a substance is largely determine by the intermolecular forces which hold its molecules together. These may included Van der Waals forces (dispersion forces), dipole-dipole …
Boiling Point/Melting Point Organic Student Doctor Network
Isotopes: Twenty-six isotopes of cobalt ranging from Co-50 to Co-75. Co-59 is the only stable isotope. Properties: Cobalt has a melting point of 1495°C, boiling point of 2870°C, specific gravity of 8.9 (20°C), with a valence of 2 or 3. Cobalt is a hard, brittle metal. It is similar in appearance how to stop being weird and annoying Molten steel is poured into a crucible, at somewhere around 2,500 degrees Fahrenheit, but another compound has recently been found that would put steel's melting point to shame.
What property determines the melting point of a substance
The melting point of gallium is used as a temperature reference point. Gallium alloys are used in thermometers as a non-toxic and environmentally friendly alternative to mercury, and can withstand higher temperatures than mercury. The alloy galinstan (70% gallium, 21.5% indium, and 10% tin) has an even lower melting point of −19 °C (−2 °F), well below the freezing point of water. how to set up metal ray satellite renderingin 3d max Notice that, although in general the melting point decreases going down the group, the melting point for magnesium is anomalously low. This is because beryllium and magnesium have different metallic structures from the other elements in the group:

How To Tell Which Element Has A Higher Melting Point
The chemical element with the highest melting point is tungsten, at 3695 K (3422 °C, 6191 °F). The often-cited carbon does not melt at ambient pressure but sublimates at about 4000 K; a liquid phase only exists above pressures of 10 MPa and estimated 4300–4700 K. Tantalum hafnium carbide
- Just look at one element and look at the boiling/melting point of all the 4 other elements that surround the element you want to know the boiling/meling point. To the Left, Right, Top, and bottom
- Determining the melting point of a compound is one way to test if the substance is pure. A pure substance generally has a melting range (the difference between the temperature where the sample starts to melt and the temperature where melting is complete) of one or two degrees.
- HOCH2CH2OH has a higher boiling point since it is more likely to form Hydrogen bonds (intermolecular ones) than CH3CH2OH (two OH groups at the edge, against one), thus having … a stronger effect
- 2012-09-08 · If asked which has highest melting/freezing point, substance with stronger intermolecular forces tend to have higher meltingfreezing point. same with boiling point. some special rules to know too: -substances that are more branched in their molecular structure tends to have a higher melting/freezing point and lower boiling point than the substances that are straight up just chains.
