As you can tell from my name, chromium is classified as a metal and their atomic mass is polar because nonmetal have higher electronegativity than metals.

The compound NCl3 is an ionic compound (metal and nonmetal), and therefore does not requi.

Chromium is a lustrous, brittle, hard metal. Its colour is silver-gray and it can be highly polished. It does not tarnish in air, when heated it borns and forms the green chromic oxide. Chromium is unstable in oxygen, it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below.

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). A metal may be a chemical element such as iron; an alloy such as Is chromium considered a metal or non-metal?

Chromium is a very shiny silver color and forms a clear oxide over time. Chromiums melting point is 1615°C (3034°F). Things are rarely made of pure chromium but lots of things are coated with it to make it shiny and not rust. Chromiums density is 7.2 g/cm 3. Chromium is nonferrous.

By most definitions, Iron and Calcium would be metals, Bromine and Nitrogen non-metals and Silicon a metalloid. Alkali metals are always 1 + (lose the electron in s subshell) Alkaline earth metals are always 2 + (lose both electrons in s subshell) Transition metal ions do not follow an obvious pattern, 2 + is common (lose both electrons in s subshell), and 1 + and 3 + are also observed \[\ce{Na^0 \rightarrow Na^+ + e^{-}} \label{1.1} onumber \] If element X is in the same period as chromium, then which of the following terms could possibly classify X? "metal," "nonmetal," and "metalloid" X must be a metal ONLY.
