A metal (from Ancient Greek μέταλλον (métallon) 'mine, quarry, metal') is a material that, when polished or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well.
metal, any of a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light. Approximately three-quarters of all known chemical elements are metals.

Jan 12, 2022 · Metal atoms differ from nonmetal ones in how well they steal valence electrons from other atoms. One might say that metals are bad thieves. Instead of capturing a neighbor’s electrons, they usually give up their own. This tendency to lose electrons is described as their “metallic character.”
The meaning of METAL is any of various opaque, fusible, ductile, and typically lustrous substances that are good conductors of electricity and heat, form cations by loss of electrons, and yield basic oxides and hydroxides; especially : one that is a chemical element as distinguished from an alloy.
There are thousands of different types and grades of metal out there, and each one is developed for very specific applications. Every day, you’ll regularly come into contact with dozens of kinds of metals. Here’s an interesting guide that will walk you through some of these common metals and where you’ll find them.
What are metals? A metal in chemistry is an element that creates positive ions (cations) readily and has metallic bonds. Metals are sometimes represented by a cloud of delocalized electrons and a lattice of positive ions. Q2
In chemistry, metal is a word for a group of chemical elements that have certain properties. It is easy for the atoms of a metal to lose an electron and become positive ions, or cations.
May 8, 2023 · What are metals? You might think Earth is a big lump of rock, hard on the outside and soft in the middle—but quite a lot of it is actually metal. What exactly is metal? Over three quarters of the chemical elements that occur naturally on our planet are metals, so it's almost easier to say what metal isn't . [1]
