Because they have interlocking electrons as the different elements' electrons have been 'tangled'

∙ 14y agoThe 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.

Why do electrovalent compounds have high melting and boiling points?
Electrovalent compounds have high melting and boiling points as they are held by very strong electrostatic force of attraction making the compound stable and therefore they require a lot of energy to break.
Why the melting point of candle wax cannot be too high?
Candles contain organic compounds with 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.
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 all minerals have high melting points?
because they are ionic compounds and have strong electrostatic force of attaction
In ionic compounds Is the melting point high or low?
They have high melting points
Are melting points of covalent compounds high or low compared to ionic compounds?
Ionic compounds have strong electrostatic force of attraction and hence have higher melting points than covalent compounds.
What are two properties of ionic compounds.?
1)brittleness 2)high melting points 3)high boiling points
Why do electrovalent compounds have high melting and boiling points?
Electrovalent compounds have high melting and boiling points as they are held by very strong electrostatic force of attraction making the compound stable and therefore they require a lot of energy to break.
Which type of compound would have the lowest melting point?
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.
Compared with the melting points of ionic compounds the melting points of molecular solids tend to be .?
Ionic compounds have a higher melting point.
What are three properties of ionic compounds within a crystal lattice?
1.Brittleness 2.High Melting Points 3.High Boiling Points
What are the characteristics of metallic compounds?
Metals have high melting points. That is because of metalic bonds.
How compared with the melting points of ionic compounds the melting points of molecular solids tend to be?
Ionic compounds have a higher melting point.
Why the melting point of candle wax cannot be too high?
Candles contain organic compounds with low melting points.
