How to distinguish between anionic cationic and netural complexes?
Answers
1.Cation and Anion
Cations are formed when a neutral atom loses one or more electrons. It has fewer electrons than the neutral atom and is therefore positively charged. Example sodium atom (Na) on losing an electron forms sodium cation, denoted by Na+, calcium atom on losing two electrons forms calcium ion, denoted by Ca2+etc.
Anions are formed when the neutral atom gains one or more electrons. It has more electrons than the neutral atom and is therefore negatively charged. For example, chlorine forms a negative chloride ion, Cl-(anion) by accepting one electron.
2. Malleability and Ductility-
Malleability is the characteristic of a metal through which a metal can be pressed or hammered into shapes without breaking. for eg:- silver and aluminium ( as they can be converted into foils without breaking)
Ductility is the characteristic of a metal through which a metal can be drawn into wires . for eg:- copper ( u can see various copper wires)
