Interpretation :
The position of the metal and non-metals in the periodic table needs to be determined. Whether there are more metallic or non-metallic elements needs to be explained.
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 distinguish the metals and non-metals.
Answer to Problem 34A
Elements placed at the left side of the periodic table are called metals, and non-metals are present on the right side of the periodic table. There are a majority of the metals in the periodic table.
Explanation of Solution
The elements of the periodic table can be categorized as metals, nonmetals, or metalloids. Metals are good conductors of heat and electricity, they can be converted into thin sheets and they are also ductile in nature that is they can be converted into thin wires. The majority of the metals are solids at room temperature except for one metal that is mercury which is liquid at room temperature. Non-metals are generally not good conductors of heat and electricity, and they are hard in nature. There are many elements found as metals in the periodic table.
The left side elements of the periodic table are termed as metals and right side elements are non-metals. The majority of the elements are metallic in nature.
