Chapter 3, Problem 35A

Interpretation Introduction

Interpretation :

The metallic element which is not solid under ordinary laboratory conditions needs to be determined.

Concept Introduction :

The periodic table is divided into two forms one is a vertical column and the other one is horizontal. The elements are differentiated as metals, non-metals and metalloids. The physical properties such as density, tensile nature, and conductors for heat and electricity help to explain about the metals and non-metals.

Answer to Problem 35A

Mercury is the only metal that is present in a liquid state at ordinary laboratory conditions.

Explanation of Solution

Metals are good conductors of heat and electricity and can be formed into sheets and wire. Most of the metals are solids at room temperature except one metal that is mercury.

The mercury is found in a liquid state at room temperature or at ordinary laboratory conditions.

Conclusion

In the periodic table left side of the elements are termed as metals, they are generally solid but only mercury is present in liquid state.
