Why do metallically bonded compounds have high melting and boiling points?

Metallically bonded compounds have high melting and boiling points due to the strength of their bonds.
Metallic bonds are very strong and therefore take a lot of energy to break, which could be heat. This is why lots of heat energy is needed to break down each individual metallic bond

∙ 11y agometallic bonds are formed by very strong electrostatic force of attraction between metals and delocalized electrons.That is why they have high melting and boiling points.

Does cast iron have metallic bonding?
Yes, cast iron is metallically bonded.
Why covelent com pound have high melting and high boiling point?
Covalent compounds have low melting and boiling points compared to ionics, because they have a weaker bond. They are only sharing electrons rather than completely giving or taking them, so they are not as strongly bonded, therefore they do not need as much thermal energy to break their bonds.
Weak dipole-dipole forces result in a what melting point?
The stronger the bonds between molecules; the higher the melting/boiling points. This makes sense if you think about it, melting/boiling is splitting up the molecules - the stronger they are bonded the more energy you will need
What is a substance with a high melting point in which all the atoms are covalently bonded?
there are number of compounds having covalent bond and high melting point. Most common example is-diamond (Made of C)
Which one has a higher boiling point a dispersion force or hydrogen bond or covalent bond or ionic bond?
Compounds with fully ionic bonds have higher boiling points than compounds without this feature, except for a few unusual, extensively three-dimensionally-bonded covalent compounds such a diamond and silica.
What is usually a property of covalently bonded compounds?
Covalent bonded compounds have generally lower melting and boiling points, are not hard, are less conductive etc.
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.

When one metal ion shares electrons with other metal ion what is it?
Part of a metallically bonded substance.

Compounds like NaCl which are bonded this way have very strong bonds and high melting points?
Ionic Bond
Does sodium exist as Na or Na 2?
Elemental sodium actually exists as a metallically bonded solid. It is customary to write the formula of solid sodium as "Na". It would not be correct to write "Na2", because in a metallically bonded solid every atom is equally strongly bonded to each of its several nearest neighbors, always more than 2, in the crystal lattice.
What temperature does matter change from a solid to a liquid?
This all depends on what type of matter it is - what element(s) are involved, as well as the pressure it is subject to. Every element and its compounds are arranged, formed, and bonded differently, causing substances to have a different melting and boiling point.
What are the charateristics of a covalent bond?
In a covalent bond electrons are shared between the atoms being bonded. Compounds containing covalent bonds are molecular, tend to have a low boiling and melting point, and they do not conduct electricity. This is because the intermolecular forces are weak , van der Waals forces. Nite that giant covalent molecules are in fact high melting.
