Question

A question before we start

The elements copper, Cu, and gold, Au, share many similarities. Both are relatively
unreactive elements. They are soft, so it is easy to bend and shape them. They are
called coinage metals because they have been made into coins by many cultures.
Copper and gold have high values as jewelry because they remain shiny for many
years.
Without looking at a periodic table, and based on what you have learned already,
what assumptions could you make about the locations of Copper and Gold on the
periodic table?
Talk with the person at your table, or closest to your table and then both type your
answer.

Answer 1

Copper (Cu) and Gold (Au) are likely located in the d-block of the periodic table, as they possess characteristics of transition metals.

Step-by-step explanation:

Based on the information given, we can make some assumptions about the locations of Copper (Cu) and Gold (Au) on the periodic table. Both Copper and Gold are described as unreactive, soft, and valuable for making coins and jewelry. These properties suggest that Copper and Gold are likely transition metals, which are found in the middle of the periodic table. Transition metals are known for their malleability, low reactivity, and high value. Therefore, we can assume that Copper and Gold would be located in the d-block of the periodic table.
