Chapter 1, Problem 1.26UKC

The six elements in blue at the far right of the periodic table are gases at room temperature. The red elements in the middle of the table are the so-called coinage metals. Identify each of these elements using the periodic table inside the front cover of this book.

Interpretation Introduction

Interpretation:

The boxes that are highlighted red in colour has to be identified from the periodic table.

Concept Introduction:

Periodic table: It is arrangement of the chemical elements, ordered by their atomic number, electronic configuration and recurring chemical properties, whose structure shows periodic trends, than all elements present usually in rows, so that elements with similar atomic structure appear in vertical columns.

Answer to Problem 1.26UKC

The blue color indicated are Noble Gas family and the elements are Helium $\left(He\right)$, Neon $\left(Ne\right)$, Argon $\left(Ar\right)$, Krypton $\left(Kr\right)$, Xenon $\left(Xe\right)$ and Radon $\left(Rn\right)$.

Red color indicated in periodic table is the coinage metals namely, copper $\left(Cu\right)$, Silver $\left(Ag\right)$, Gold $\left(Au\right)$.

Explanation of Solution

Let us consider the given statement of periodic table.

Above periodic table, and corresponding blue color indicated by Noble gas elements like Helium $\left(He\right)$, Neon $\left(Ne\right)$, Argon $\left(Ar\right)$, Krypton $\left(Kr\right)$, Xenon $\left(Xe\right)$ and Radon $\left(Rn\right)$.

Red color indicated in the periodic table is the coinage metals namely, copper $\left(Cu\right)$, Silver $\left(Ag\right)$, Gold $\left(Au\right)$.

Conclusion

The elements were identified given the periodic table with respective colors.
