Unique Properties of Metals, Nonmetals, and Metalloids
In the periodic table, we can group elements into three main types: metals, nonmetals, and metalloids. Each type has special features that make them different from each other.
Metals
Metals are mostly found on the left side and in the center of the periodic table. They make up about 75% of all elements. Here are some cool things about metals:
Conducting Electricity: Metals are great at carrying electricity because they have electrons that can move freely. For example, copper is a good conductor.
Conducting Heat: Metals also transfer heat well. Silver is the best at this.
Shiny Surface: Most metals are shiny and reflect light, making them look nice.
Flexible and Stretchy: Metals can be shaped into thin sheets (we call this malleability) or stretched into wires (this is ductility). Gold can be hammered into very thin sheets!
High Temperatures: Metals generally melt and boil at very high temperatures. For example, tungsten has an extremely high melting point.
Nonmetals
Nonmetals are mostly on the right side of the periodic table and account for about 17% of the elements. They have some different traits:
Poor Conductors: Nonmetals do not conduct electricity well and are often insulators. For instance, sulfur is not a good conductor.
Brittle: Nonmetals tend to break easily when you try to bend them.
Different States: Nonmetals can be gases (like oxygen), liquids (like bromine), or solids (like carbon) at room temperature.
Lightweight: Many nonmetals are lighter than metals. For example, helium is the lightest element.
Lower Temperatures: Nonmetals usually melt and boil at much lower temperatures than metals. For example, nitrogen boils at a very cold temperature.
Metalloids
Metalloids have properties that are in between metals and nonmetals. They are found along a line in the periodic table. Here are some important features of metalloids:
Semiconductors: Metalloids, like silicon, can conduct electricity better than nonmetals but not as well as metals.
Brittle and Shiny: Metalloids can look shiny like metals, but they can also break easily like nonmetals.
Different Reactions: Depending on how they react with other chemicals, metalloids can act like either metals or nonmetals.
Moderate Temperatures: Metalloids have melting and boiling points that fall between those of metals and nonmetals.
By learning about these unique properties, we can better understand how different elements behave and how to organize them in the periodic table.
