The stainless steel tube atom relies on this combination of positive ions and the attraction of electron gas, which can briefly explain some of the characteristics of the metal. For example, there is a power difference between the two ends of a metal wire, and free electrons immediately flow in a certain direction, generating current is the reason why metals have good electrical conductivity. As for sodium chloride - table salt, there are no free electrons and poor conductivity. In addition, under the action of external force, the shape of the metal is changed by the translation and sliding of the positive ion layer to each other, but the positive ions that have changed the original position are still connected with the surrounding free electrons, and the stainless steel pipe has good forgability. Taking table salt as an example, under external force, the relative position of positive sodium and negative ion chlorine is slightly changed, and the ion with the same electrical properties meets and rebounds, which is manifested as the rupture of salt particles.
The way the atoms inside the stainless steel tube are combined can also explain other properties of the stainless steel tube such as thermal conductivity, thermoelectrics, and metallic luster.
