What are complex ions?
Complex ion is a small particle of matter called a molecule that carries a positive or negative charge. Complex ions are made of a group of atoms connected together into one, larger particles. Ions are simply defined as molecules that bear either positive or negative charge, which means there are more total protons than electrons or vice versa. Complex ions must be made of more than one type of atom and can be divided into two or more smaller ions. All complex ions contain at least one metal or positively charged atom associated with one or more negatively charged ions. Atom is the smallest unit of pure element that may exist. For example, if a piece of pure gold is over and over again until the smallest microscopic spots are achieved, the result is the only gold atom. This atom would be made of 79 positive protons grouped into the center core and surrounded by Acloud 79 negative electrons. If the gold atom gives up one of his negAtive electrons, he will be left with a positive charge and will then be considered an ion.
In chemistry, metal is an element or type of atom that carries a positive charge. Looking at the periodic table, the elements are left and in the middle of metals, with the exception of hydrogen. Complex ions occur when the electron is connected from one of these metals with another atom or molecule.
The general structure of complex ions is a centrally located metal atom surrounded and connected with other ions. Together metal and surrounding ions form a single larger piece called molecule. The overall charge on the molecule is either positive or negative, but not neutral.
One of the common complex ions is sulphate ion. This ion consists of one sulfur atom surrounded by four oxygen atoms. The sulios of the IS acts like a metal, not because it is shiny, strong and malleable as everyday metals, but because sulfur distributes electrons surrounding atoms Kysland leave it with a positive charge. The sulphate ion carries a charge of the negative two, because it has two other total electrons than the protons and the charge is the definition of the ion.
