In ionic compounds Is the melting point high or low?
They have high melting points
Do simple molecular substances have high or low melting and boiling points?
Yes, molecular solids have relatively low melting points.
What are the 2 halogens with the highest melting points?
Melting points increase with atomic weight for elemental halogens (the second-most right column in a periodic table). The heavier the atom, the harder to turn it into a liquid. The lightest halogens, such as Florine (F) and Chlorine (Cl) are gasses at room temperature, having "melted" and "boiled" at lower (colder) temperatures. The two heaviest halogens are Iodine (I) and Astatine (At). Astatine is very rare, but Iodine is common and is a solid at room temperature. The have the highest melting points of halogens. Remember, F down to At increase in melting points. F and Cl are gases, so they have low melting point. Br is a liquid, so it has a higher melting point. I and At are solids so it takes more heat to melt them.
What are three properties of ionic compounds within a crystal lattice?
1.Brittleness 2.High Melting Points 3.High Boiling Points
Do ionic bonds melt at a low melting point?
No. They have very high melting points because they are extremely strong. This is because of the transfer of electrons between the atoms in the bond. Molecular generally have low melting points.

Yes, molecular solids have relatively low melting points.
Do nitrogen and oxygen have very high melting points?
No, they have very low melting.
Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
Does a metal have a high or low melting point?
All metals have different melting points but they are all high
Do actinides have high or low melting points?
higher M.P
Are the elements in the boron group high-melting?
It varies. Boron and thallium both have relatively high melting points while gallium and indium have very low melting points.
Do the molecules of alkanes have strong intermolecular forces and high melting points?
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.

All metals are hard and have high melting points?
No, the alkali metals are pretty soft and the metals cesium, gallium, and mercury have very low melting points.
