Chapter 2: Problem 40

The elements of group 4 A show an interesting change in properties moving down the group. Give the name and chemical symbol of each element in the group, and label it as a nonmetal, metalloid, or metal.

Short Answer

Expert verified
The elements in Group 4A are Carbon (C) - Nonmetal, Silicon (Si) - Metalloid, Germanium (Ge) - Metalloid, Tin (Sn) - Metal, and Lead (Pb) - Metal.

Step by step solution

01

Identify the elements in Group 4A

To identify the elements in Group 4A, consult a periodic table. Group 4A elements are Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb).
02

Determine the chemical symbols

Once the elements in Group 4A are identified, write down their chemical symbols. These are: 1. Carbon - C 2. Silicon - Si 3. Germanium - Ge 4. Tin - Sn 5. Lead - Pb
03

Categorize the elements as nonmetal, metalloid, or metal

Now, classify these elements into one of the three categories: nonmetal, metalloid, or metal. 1. Carbon (C) - Nonmetal: Carbon has various allotropes, including diamond and graphite, and it forms covalent bonds; it does not possess the typical metallic properties. 2. Silicon (Si) - Metalloid: Silicon has properties of both metals and nonmetals. It is used as a semiconductor in electronics. 3. Germanium (Ge) - Metalloid: Germanium also has properties of both metals and nonmetals. It is also a semiconductor material used in electronics. 4. Tin (Sn) - Metal: Tin is a soft, malleable, and ductile metal with a shiny metallic appearance. 5. Lead (Pb) - Metal: Lead is a heavy, dense, and soft metal which is highly malleable and ductile. It has a blueish-white appearance when freshly cut, but its surface tarnishes over time.
