Properties Of Metals

Physical Properties

Properties of a metal include shininess, malleability, ductility, and conductivity. A malleable is a material that can be hammered or rolled into flat sheets and other shapes. Ductile is a material that can be pulled out or dawn into a long wire. Conductivity is being able to transfer heat or electricity to another object. Most metals are good conductors, but few metals are magnetic. Good conductors of heat and electricity may clang when they hit .When some metals are kept are room temperature they can form into solids.(Frank,88)



Chemical Properties
Metals are very reactive. Reactivity is the ease and speed with which an element combines and reacts with other elements and compounds.(Frank,89) Metals usually react when an element easily gains or loses electrons, which is used for bonding. They react with acids to form salts. Corrosion is the destruction of a metal. Corrosion is the gradual wearing away of metals due to a chemical reaction. Some metals are resistant to erosion. For example, chromium is a metal resistant to erosion, which is used for bath fittings.(Frank,89)

Metals in the Periodic Table
Metals placed in the same group or family has the same properties. As you move across the table from left to right the reactivity of metals decrease. The blue part of the Periodic table are the metals.(Frank,90)

Alkali Metals
Alkali metals are the first group in the periodic table. They react with elements by losing one electron. These elements are so reactive that they aren’t uncombined in nature.(Frank,90) The uncombined elements are shiny and soft. So soft that they could be cut with a butter knife.
Alkaline Earth Metals
Alkaline metals are the second group in the periodic table. Each is fairly hard, gray white, and a good conductor of electricity. Since they are in the second group of the periodic table they react by losing 2 electrons. These metals are not as reactive as the metals in group 1.(Frank,92) The two most important alkaline earth metals are magnesium and calcium. This is because mixing magnesium and a small amount of aluminum can make a strong but light weight material. In result making mechanical vehicles that we use in our everyday lives. Calcium is one of the most important life essentials. Calcium compounds come from milk and dairy products that help our teeth and bones get stronger.(Frank,92)
Transition Metals
These metals are in groups 3-12. The characteristics that describe these metals are hard and shiny. They are also good conductors of electricity. And they are less reactive then the metals that are in groups 1 and 2. The thing about transition metals is some are important to your health.(Frank,92)
Metals in Mixed Groups
In groups 13-15 some elements are metals. These metals are less reactive then the metals towards the beginning of the periodic table.(Frank,92)

Lanthinides
One of the two rows that are located at the bottom of the periodic table are called lathanides. These metals are soft, malleable, and shiny, with high conductivity.(Frank,92) These elements are mixed with common metals to make alloys. An alloy is a mixture of an element with at least one other element, usually another metal. These types of elements are hard to separate because they are very alike.

Actinides
The elements below the lathanides are called actinides. Actinium, thorium, protactinium, and uranium are the only elements that occur naturally on Earth. One of these elements called Uranium is used to produce energy that is used in nuclear power plants. The nuclei of these elements are unstable meaning they break apart faster into smaller nuclei.(Frank,94)

Synthetic Elements
Synthetic elements are particles with atomic numbers higher than 92. Sometimes scientists use particle accelerators which move atomic nuclei faster and faster until they have reached high speeds. (Frank,94) This results in elements with atomic numbers above 95. Sometimes these elements can go so fast that with enough energy they can combine into a nucleus. The process of synthesizing elements can be very difficult, but it results into a success that makes elements better by being more powerful.
