Features of the metal atomic structure of stainless steel tubes

Metals and nonmetals are made up of many atoms. Each atom consists of a small, positively charged nucleus and one or several negatively charged electrons. The electrons are distributed in the electron layers outside the nucleus and rotate around the nucleus at high speed. In this way, atoms can also be seen as planets in the small universe orbiting the sun. Each electron has a certain load, and the sum of the electrons carries a load equal to the number of positive charges carried by the nucleus, so the whole atom does not show electricity, that is, neutrality. The nuclei of various elements of stainless steel tubes have different positive charge numbers, so the number of electrons of each element is also different. For example, a copper atom has a nuclear charge number of 28 and 28 electrons outside the nucleus, while a chlorine atom has a nuclear charge number of L7 and 17 electrons outside the nucleus.
