Because they have interlocking electrons as the different elements' electrons have been 'tangled'
strong intermolecular forces, such as ionic or covalent bonds, which require a significant amount of energy to break and melt the compound. These forces hold the atoms or ions together in a fixed lattice structure, contributing to the high melting point.
The ionic compound usually have high melting points due to formation of three dimensional lattice but some covalent compounds with 'Giant structure' also show very high melting point as Diamond.
Compounds with high melting points have ionic bonds. This is because atoms with ionic bonds show strong attractions to other ions in their vicinity.
Not all compounds have high melting points and high boiling points.

Why do electrovalent compounds have high melting and boiling points?
Electrovalent compounds have high melting and boiling points because they have strong electrostatic forces of attraction between the positively charged metal ions and negatively charged non-metal ions. These forces require a significant amount of energy to overcome, resulting in high melting and boiling points for these compounds.
How is high melting and boiling points related to the structure of the compounds?
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
Why do mixtures not have sharp melting points and boiling points?
Because they are not pure compounds !
What kind of bond allows creates compounds with high melting points?
Ionic bonds are typically responsible for creating compounds with high melting points. In ionic bonding, atoms transfer electrons to achieve a full outer shell, resulting in a strong attraction between positively and negatively charged ions. This strong electrostatic force requires more energy to break the bond and hence, compounds with ionic bonds tend to have 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.
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 two properties of ionic compounds.?
1)brittleness 2)high melting points 3)high boiling points
Which type of compound would have the lowest melting point?
Ionic compounds typically have higher melting points compared to molecular compounds. Among molecular compounds, those with weaker intermolecular forces, such as van der Waals forces, tend to have lower melting points due to their easily broken bonds.
Why do electrovalent compounds have high melting and boiling points?
Electrovalent compounds have high melting and boiling points because they have strong electrostatic forces of attraction between the positively charged metal ions and negatively charged non-metal ions. These forces require a significant amount of energy to overcome, resulting in high melting and boiling points for these compounds.
Compared with the melting points of ionic compounds the melting points of molecular solids tend to be .?
Ionic compounds have a higher melting point.
How is high melting and boiling points related to the structure of the compounds?
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
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 the ionic compounds generally have high melting points?
well I dk geti don't know
What causes ionic compounds to have high melting point?
Ionic compounds have high melting points because they are made up of ions held together by strong electrostatic forces of attraction. These forces, known as ionic bonds, require a significant amount of energy to break, resulting in high melting points.
Where can you find a table of melting points for compounds?
Here's a chart of elemental melting points...not compounds. http://www.chemicalelements.com/show/meltingpoint.html
Are melting points of covalent compounds high or low compared to ionic compounds?
Melting points of covalent compounds are generally lower than those of ionic compounds. This is because covalent compounds have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds, so they require less energy to break apart the molecules.
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.
