Chapter 2: Problem 44

The elements of group 4 \(\mathrm{A}\) 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 of Group 4A and their classifications are as follows: 1. Carbon (C) - Nonmetal 2. Silicon (Si) - Metalloid 3. Germanium (Ge) - Metalloid 4. Tin (Sn) - Metal 5. Lead (Pb) - Metal

Step by step solution

01

Find the Group 4A Elements in the Periodic Table

Look at the Periodic Table and locate Group 4A (also known as Group 14). The group starts with carbon at the top and ends with lead at the bottom.
02

List the Elements and Their Chemical Symbols

We can list down the elements in Group 4A along with their respective chemical symbols: 1. Carbon (C) 2. Silicon (Si) 3. Germanium (Ge) 4. Tin (Sn) 5. Lead (Pb)
03

Classify the Elements as Nonmetal, Metalloid, or Metal

Based on their properties, we can classify the elements in Group 4A as follows: 1. Carbon (C) - Nonmetal 2. Silicon (Si) - Metalloid 3. Germanium (Ge) - Metalloid 4. Tin (Sn) - Metal 5. Lead (Pb) - Metal Now, we have provided the names and chemical symbols of each element in Group 4A as well as classified them as a nonmetal, metalloid, or metal.
