How can metal ions be identified
Web22 de jan. de 2024 · On heating, every metal ion has its unique color at a specific wavelength. When metals are heated on flame, their electrons jump to higher energy levels. On returning to their original energy level, they emit energy that can be seen in the form of colors by the naked eye. Based on their colors, metal ions can be easily identified in a … WebMetals are generally identified by their properties. Most of the metals have a luster (shiny appearance). Most of the metals are good conductors of electricity. So if some unknown …
