A method for experimentally determining isotopic masses and isotopic abundances . A sample of an element is converted into a stream of ions and passed through an electromagnetic field. A plot showing the results of a mass spectrometry experiment, which shows the presence of particles with different masses as a series of sharp, separate peaks. Compare with nonmetal and metalloid . A metal is a substance that conducts heat and electricity, is shiny and reflects many colors of light, and can be hammered into sheets or drawn into wire.
Metals lose electrons easily to form cations .
Compare with isotopic abundance . The average fraction of atoms of a given isotope of an element on Earth. 1. having no net electrical charge. An elementary particle found the atomic nucleus of all stable atoms except the hydrogen-1 atom. Neutrons have no charge and have a mass of 1.008665 daltons .
