Elements that have sim ilar properties are arranged in groups in vertical columns. Horizontal rows are called periods. Chromium is a steely-grey, lustrous, hard and brittle metal[4] which takes a high polish, resists tarnishing, and has a high melting point. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Chromium is unstable in oxygen, it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below.

Chromium metal or nonmetal

Examples of non-precious (base) dental alloys. View Homework Help - CHAPTER 5 from CHEM 2040 at University of Central Florida. CHAPTER 5 Metal + non-metal = ionic bonding Nonmetal + nonmetal = covalent bonding Metal + metal = metallic bonding 1. 2013-01-03 · The terms metal and nonmetal are really descriptive of ways atoms react; metals lose electrons, nonmetal gain them. Another category of atom is a noble gas - atoms that already have the full valence shell that metals and nonmetal react to acquire.

range of metals and non-metals (e.g. cyanides, hypochlorite, AOX and peroxides), Metals commonly recovered include copper, nickel, chromium and zinc.

The metals are on the left side and nonmetals on the right. Metalloids tend to sit on both sides of the divide, especially the lower half (not every chemist agrees on which elements are metalloids). By most definitions, Iron and Calcium would be metals, Bromine and Nitrogen non-metals and Silicon a metalloid.

By signing up, you'll get thousands of step-by-step solutions to your homework questions. You can also ask A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires).

Chromium is located in group 4 in the transition metals . Lead is located in group 6 and is under the staircase. Hope that helps!

It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.
