In metal crystals, free electrons move through and are not exclusive to a metal ion but common to the entire metal crystal. These free electrons interact with all the metal ions to form some kind of bond, an action known as a metallic bond. Since only a few valence electrons can be used to form bonds, metals, when forming crystals, tend to form extremely tight structures so that each atom has as many adjacent atoms as possible (metal crystals generally have high coordination numbers and tightly packed structures), so that the electron energy levels can be overlapped as much as possible to form metallic bonds.
The change from a block to a powder changes the number of adjacent atoms for each atom, so the metal bond is broken.

Inside the metal, there are many metal cation stations in the middle, and then many electrons revolve around them.
The gravitational and repulsive forces between metal cations and electrons are metallic bonds.
Because you're a big piece of metal, the electronics are running around very freely.
And then you suddenly grind him into powder.
A lot of electrons playing outside can't find their own metal cations. Then their interaction force will be wooden. Then the metal bond is broken.
Figuratively speaking, it means that your child was abducted and trafficked while playing outside. Is the family destroyed? That's it
Just understand, thank you
-
Metal blocks, also known as metal crystals, rely on metal bonds to bind metal atoms, metal ions, and free electrons together!
If you cut a metal block, you will naturally widen the distance between the metal ions and the free electrons, and the ionic bond will be broken.

No Destruction: The metal melts, but the state changes, but the essence of the substance does not change, and the metal bond is a bond, and the bond energy is large, and it can be broken by melting.

-
Without breaking, there are still delocalized bonds of metal cations and free electrons, but the role of the bonds is smaller. If you add the power supply, it is found that the melted metal can still conduct electricity.

About what exactly is being destroyed.
The main thing is what matter is made of.
1.Matter is made up of atoms. (There is no molecular structure in the substance).
Breaking covalent bonds (various non-metals, such as diamond. But when graphite melts, the situation is more complicated, not only destroying the covalent bonds)
or breaking metal bonds (various metals).
2.Matter is made up of ions.
Break ionic bonds. (Various ionic compounds, e.g., NaCl).
3.Matter is made up of molecules.
Destroy van der Waals Force. (e.g. iodine).
-
No, a metal bond is caused by the force between the metal ion and the free electron, and the melting does not destroy it.

In Hutcheson's experiments, when he turned up the electromagnetic energy to produce more resonance, the electron orbitals in the outer layer of the metal bond would be destroyed by the resonance, causing the metal atoms to oscillate incessantly, and as a result, the intrinsic framework between the atoms began to shake, and the whole metal formed a soft, trembling "metal jelly", which looked like the metal would melt automatically at normal room temperature. When the electromagnetic field is removed, the metal block begins to calm down from the momentary "nightmarish" restlessness, "calm down", and the metal bonds begin to form again between the neighboring atoms, and the atoms "shake hands" again to form a stable twisted shape. This is exactly what we see as the Hutchison effect.
In fact, Hutchison developed a new form of electrochemistry that changes the chemical properties of matter by changing the resonant frequency of the electron orbital. Through Gegnon's interpretation, we can transform the unimaginably miraculous and complex means of realizing the Hutchison effect into a simple explanation – an explanation that conforms to classical physics. Using these resonant frequencies, you can operate the instruments used by Hutchison and learn the following interesting techniques:
You can make the chemical bonds in an object stronger, increasing the strength and resistance of the entire material, or conversely, you can make the chemical bonds weaker, maybe a piece of iron turning into a pile of powder at room temperature. And there's something else: by adjusting the frequency properly, you can make one substance behave like another, or maybe exhibit properties that we haven't seen so far
Mimicking atoms, elements, and compounds that have never existed in nature. If a piece of steel imitates a feather, then there is nothing surprising that it flies.

Because the light is reflected many times on the surface of the metal powder, the number of outgoing photons becomes smaller (trapped inside, or attenuated), so the metal powder tends to be darker. This is similar to ice and snow, one transparent and one white.
-
Do you know what iron oxide is? Iron powder is oxidized before it will appear black, and gold and silver are more resistant to oxidation, so it will be the original color.
-
Metal powders are almost overwhelmingly black due to the scattering of light. For example, pure iron and silver are silvery-white, but when ground into powder, they are both black.
-
It's a difficult question, what is the size of your metal powder particles? Even non-ferrous metals such as gold and silver are black when the particles are small because their metal bonds are broken, and only a few metal powders are still white (such as magnesium and aluminum).

The melting and boiling points of metals depend on the strength of the metal bonds. Generally speaking, the smaller the radius of a metal ion, the more charge the ion carries, the stronger its metallic bonds, and the higher the melting and boiling point of the metal.
This is not something that can be explained in one or two sentences, so I will briefly talk about it. 1. The valence state of the ions is different, the color is different, the valency is different, the energy of the ions is different, and the colors displayed are different, such as ferric iron is green in water, and trivalent iron is yellow 2. 3. The state of the ions is related, the copper ions in the solid copper oxide are black, while the copper ions in the aqueous solution are blue. >>>More
This is because nitric acid is very oxidizing.
In fact, hydrogen can be generated, and when the concentration of nitric acid is relatively small, it may be hydrogen. >>>More
The reason why traditional Chinese medicine can not be boiled in a metal pot is because the metal pot is heated unevenly, there is no way to keep warm well, and it is not conducive to the preservation of heat-resistant components, the active ingredients in many plant Chinese medicines will have a chemical reaction with the iron ions in the metal pot, and there is no way to dissolve in water precipitate, which can not be absorbed by the body, and the alkaloid components in the Chinese herbal medicine must be combined with tannic acid to be dissolved in water. There is no way to dissolve the alkaloids, which affects the efficacy of the drug, so it cannot be boiled in a metal pot.
Under the action of the original electric field, the metal charge moves, creating an induced electric field. >>>More
If the porcelain tooth is made of chemically inert metal, because of its chemical instability, the metal ions are easy to be freed out and deposited in the gums or tooth root hard tissues adjacent to the porcelain teeth, making the gums at the contact site black. This is the main cause of darkening of the gums when porcelain teeth are made. In addition, if the doctors and technicians are not in place, the edges of the porcelain teeth are not suitable, they are located on the gums or do not fit well with the natural teeth, and there is a gap between the natural teeth and the natural teeth after being worn on them, and then the porcelain teeth will have a series of problems, including the black line of the gums. >>>More
