Chapter 2: Problem 99

The elements in one of the groups in the periodic table are often called the coinage metals. Identify the elements in this group based on your own experience.

Short Answer

Expert verified
The coinage metals are elements in Group 11 of the periodic table, consisting of Copper (Cu), Silver (Ag), and Gold (Au). These metals share properties such as ductility, malleability, and resistance to corrosion, making them suitable for minting coins. Roentgenium (Rg), also a Group 11 element, is not considered a coinage metal due to its radioactivity and instability.

Step by step solution

01

Understand the properties of coinage metals

Coinage metals share some distinct properties that make them suitable for minting coins. They are typically ductile and malleable, which makes it easy to shape them into coins. Additionally, they don't react easily and are resistant to corrosion or damage from the environment, meaning coins made from these metals last for long periods.
02

Identify the position of coinage metals in the periodic table

To find the coinage metals in the periodic table, we need to know which group they belong to. The coinage metals are elements in Group 11 of the periodic table, which means they all have one electron in their outermost s orbital.
03

Find the elements in Group 11

Now that we know the coinage metals are in Group 11, we can identify the elements in this group. In the periodic table, Group 11 elements are: 1. Copper (Cu) 2. Silver (Ag) 3. Gold (Au) 4. Roentgenium (Rg)
04

Identify the coinage metals based on their usage

Based on historical usage and their properties, the coinage metals are: 1. Copper (Cu) 2. Silver (Ag) 3. Gold (Au) Roentgenium (Rg) is not considered a coinage metal due to its radioactivity and instability, making it unsuitable for minting coins.
