Question

How many metals, nonmetals and metalloids are there on the periodic table$?$

Answer 1

The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number to the element with the highest atomic number. The elements which exhibit the highest degree of metallic behaviour are known as metals. Non-metals are the elements which do not possess any metallic behaviour. The elements that have properties of both metals and nonmetals are called metalloids.

Complete answer:
The total number of elements in the periodic table is $118$.
The metalloids separate the metals and nonmetals on a periodic table. Elements to the left of the line are considered metals. The elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids. Examples of nonmetals are oxygen, chlorine, and argon. Examples of metalloids are boron, silicon, and arsenic. Examples of metals are iron, tin, sodium, and plutonium.
The total number of Metals in the periodic table is $92$.
The total number of Nonmetals in the periodic table is $20$.
The total number of Metalloids in the periodic table is $6$.

Note:
The atomic number of an element is the number of protons in the nucleus of an atom of that element. Metals are generally shiny, malleable, hard and also good conductors of electricity. Non-metals do not conduct heat or electricity very well and are typically brittle. Metalloids share characteristics of both metals and nonmetals and are also called semimetals.
