Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).

What are 5 physical properties of metals?

Metal Physical Properties:

  • Lustrous (shiny)
  • Good conductors of heat and electricity.
  • High melting point.
  • High density (heavy for their size)
  • Malleable (can be hammered)
  • Ductile (can be drawn into wires)
  • Usually solid at room temperature (an exception is mercury)
  • Opaque as a thin sheet (can't see through metals)

What are the characteristics of alkali metals?

Characteristics of alkali metals are:

  • High reactive metals.
  • Not found freely in nature.
  • Stored in a mineral oil solution.
  • Low melting points.
  • Low densities (lower than other metals)
  • Low electronegativity.
  • Low ionization energy.
  • React easily with halogens.

What are the uses of metals?

Uses for Metals and Nonmetals

  • Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.
  • Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.

What are the physical and chemical properties of alkali metals?

The alkali metals are a group of chemical elements in the periodic table with the following physical and chemical properties:

  • shiny.
  • soft.
  • silvery.
  • highly reactive at standard temperature and pressure.
  • readily lose their outermost electron to form cations with a charge of +1.

What are the properties of nonmetals and metals?

DensityHigh (they feel heavy for their size)Low (they feel light for their size)
Malleable or brittleMalleable (they bend without breaking)Brittle (they break or shatter when hammered)
Conduction of heatGoodPoor (they are insulators)

What are the 4 properties of nonmetals?

Summary of Common Properties

  • High ionization energies.
  • High electronegativities.
  • Poor thermal conductors.
  • Poor electrical conductors.
  • Brittle solids—not malleable or ductile.
  • Little or no metallic luster.
  • Gain electrons easily.
  • Dull, not metallic-shiny, although they may be colorful.

What are common metals?

Aluminum, cadmium, chromium, copper, iron, lead, nickel, tin, zinc, or any combination of these elements are considered common metals.

What are the different metals?

What is the cheapest metal on earth?

Iron eventually became the least expensive metal on Earth. That's because iron, as found in ores, is our most plentiful element by mass.

What are the five common alloys?

5 Common Alloying Elements

  • Chromium.
  • Molybdenum.
  • Vanadium.
  • Manganese.
  • Nickel.

What are the 2 types of alloys?

There are two main types of alloys. These are called substitution alloys and interstitial alloys. In substitution alloys, the atoms of the original metal are literally replaced with atoms that have roughly the same size from another material. Brass, for example, is an example of a substitution alloy of copper and zinc.

What is unique about metals?

Metals are primarily shiny, hard solids that are good conductors of heat and electricity. There are exceptions. For example, gold is very soft and mercury is a liquid. However, there are no metals that act as insulators rather than conductors.
