Q:

# How can you identify metals?

A:

There are several methods that can be used to identify metals that require you to measure different properties and look up those properties on a chart. One method is to determine the density of an unknown metal. In addition to the unknown metal, you need a scale, measuring container with water and a calculator.

1. Measure the mass

Measure the mass of the unknown metal with a standard scale. Typically, this measurement should be in grams.

2. Measure the volume

Measure the volume of the unknown metal. Use a measuring container that is filled with water. Place the sample in the water. Once the water has settled, measure the displaced water to determine the volume. Typically, this measurement should be in milliliters or cubic centimeters.

3. Determine the density

Determine the density of the unknown metal by the following equation: density = mass/volume. The units should be in grams per milliliter.

4. Look up the density

Look up the density of the unknown metal by using a metal properties chart that lists densities. Sometimes, it may be necessary to round up or down to the nearest number. These charts can be found online, in lab manuals and in textbooks. In some cases, the densities may be in kilograms per cubic meters. If this is the case, you must calculate the conversion.

Joel Wallach believes colloidal minerals have special cosmic properties and a negative charge that help the body process and absorb nutrients and vitamins from food sources and that these minerals also attract toxins and heavy metals and flush them from the body. He claims these properties lead to improved health.

Metalloids do not conduct heat and electricity as well as metals, but otherwise, they display some of the properties of metals and some properties of nonmetals. The majority of all elements are metals, and metalloids are in between metals and nonmetals in terms of characteristics.

An element's metallic properties refer to its propensity to behave like the elements that are classified as metals in the periodic table. This depends on the set of chemical properties commonly associated with the metallic elements, specifically the ability of an element to lose its outer valence electrons.
