The elements of group 14 show an interesting change in properties moving down the group. Give the name and chemical symbol of each èlement in the group and label it as a nonmetal, metalloid, or metal.

Group 14 elements are the elements found in the 14th column of the periodic table. They are: 1. Carbon (C) 2. Silicon (Si) 3. Germanium (Ge) 4. Tin (Sn) 5. Lead (Pb)

Now, we will categorize each element as either a nonmetal, metalloid, or metal based on their properties: 1. Carbon (C) - Nonmetal: Carbon is a nonmetal because it cannot conduct electricity and does not have metallic luster. It is also a good oxidizing agent and its most common forms, diamond and graphite, are known for their hardness and high melting points, respectively. 2. Silicon (Si) - Metalloid: Silicon is a metalloid because it has properties of both metals and nonmetals. It is a poor conductor of electricity, has a metallic luster, and is quite hard. Silicon is often used in semiconductor applications due to its unique properties. 3. Germanium (Ge) - Metalloid: Germanium is also a metalloid, as it has properties of both metals and nonmetals. It is a poor conductor of electricity and is often used in semiconductor applications. Germanium has a metallic luster and is quite hard. 4. Tin (Sn) - Metal: Tin is a metal due its ability to conduct electricity and heat. It has a metallic luster and is malleable, meaning it can be bent and shaped without breaking. 5. Lead (Pb) - Metal: Lead is a metal because it can conduct electricity and has a metallic luster. It is malleable and has a low melting point compared to other Group 14 elements.
