Elements named after a property

Several elements were named directly for an observable property at the moment of discovery: a colour, a smell, a weight, a reactivity or a behaviour. Examples include chlorine (Greek chloros, pale green), bromine (Greek bromos, stench), argon (Greek argos, lazy) and indium (Latin indicum, indigo). This page lists every element whose name describes one of its physical or chemical traits.
