How are elements classified as metals?

The elements can be classified as metals nonmetals or metalloids. Metals are good conductors of heat and electricity and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire).

Which metal is the strongest?

Tungsten has the highest tensile strength of any pure metal – up to 500 000 psi at room temperature. Even at very high temperatures over 1 500°C it has the highest tensile strength. However tungsten metal is brittle making it less useable in its pure state.

What are the two main classification of elements?

Elements are typically classified as either a metal or nonmetal but the dividing line between the two is fuzzy. Metal elements are usually good conductors of electricity and heat. The subgroups within the metals are based on the similar characteristics and chemical properties of these collections.

What is an element and how are elements classified Class 8?

A substance which cannot be broken down into two or more simpler substances by chemical reactions is called an element. For Example: Iron hydrogen helium oxygen phosphorus sulphur chlorine bromine gold silver mercury aluminium etc.

WHO classified the known elements into eight groups?

British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. He arranged the elements in eight groups but left no gaps for undiscovered elements.

Which classification do most elements are classified?


The majority of elements in the periodic table are classified as metals. The transition metals lie in the center of the table spanning groups three through 12.

WHO classified elements first?

The earliest attempt to classify the elements was in 1789 when Antoine Lavoisier grouped the elements based on their properties into gases non-metals metals and earths. Several other attempts were made to group elements together over the coming decades.
