All ionic compounds form crystals. So far as I know, there are no exceptions to this. Again, salts like to form crystals because when you have a whole bunch of little electrical positive and negative charges all stuck together, they seem to like to bunch into little stacking groups. The arrangement that these ions like to stack into is different, and is referred to as the "unit cell". There are ten or so different general shapes of unit cells. When you get to graduate school, ask me about them. For high school classes, it's really not all that important. Ionic compounds tend to have high melting and boiling points. When I say "high", what I mean is "very, very high." Most of the time, when you work with ionic compounds in a chemistry class, the melting point is hot enough that you can't melt them with a Bunsen burner. So, why are these temperatures so high? Well, it has to do with the way that ionic materials are held together. Remember how we said above that ionic compounds form crystals? These crystals are basically just great big blocks of positive and negative charges all stuck together. To break the positive and negative charges apart, it takes a huge amount of energy. This means that if we heat up the compound to add energy, it takes a huge amount of energy to break it apart.

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.


Do simple molecular substances have high or low melting and boiling points?

Simple molecular substances typically have low melting and boiling points. This is because the weak intermolecular forces, such as London dispersion forces, in simple molecular substances are easily overcome compared to the stronger bonds in ionic or metallic substances.


In ionic compounds Is the melting point high or low?

In general, ionic compounds have high melting points due to the strong electrostatic forces holding the ions together in a lattice structure. This results in a significant amount of energy required to break these bonds, leading to high melting points.


What are the effects of covalent and ionic substances?

well ionic substances are solid at room temperature,they are generally soluble in water ,they have high melting and boiling points,while covalent substances are generally liquid and gases at room temperature,non-polar covalent substances are generally insoluble in water while polar covalent are generally soluble in water


Do ionic solids have low melting points?

Ionic solids typically have high melting points due to the strong electrostatic forces binding the positive and negative ions together in a lattice structure. When heated, these bonds must be overcome, requiring a significant amount of energy, resulting in high melting points.

What type of bonds have high melting point and are soluble in water?

Ionic bonds have high melting points and can be soluble in water. Ionic compounds have strong bonds between positive and negative ions, leading to high melting points, and they can dissolve in water due to the attraction between the ions and the water molecules.


What are two properties of ionic compounds.?

1)brittleness 2)high melting points 3)high boiling points


Is A compound with a high melting point ionic or covalent?

A compound with a high melting point is more likely to be ionic rather than covalent. Ionic compounds have strong electrostatic forces between oppositely charged ions, resulting in high melting points. Covalent compounds typically have lower melting points because they are held together by weaker intermolecular forces.


Why do ionic compound have such high melting and boiling points?

Ionic compounds are basically the combination of a metal and a non-metal. However, its high melting points and boiling points are part of the physical properties of ionic compounds, and high heat is usually required to break the bonds of ionic compounds. The ions which are held together by strong electrostatic force of attraction may results in high melting point and boiling point.


Do ionic bonds form lower melting points?

No, ionic compounds have high melting and boiling points. This is due to the strength of the electrostatic attraction between the positively-charged and the negatively-charged ions.
