Answer 1

Answer:

Elements are mainly classified into metals and non-metals. Metals are lustrous, malleable, ductile and are good conductors of heat and electricity. They are the solids at room temperature only except Mercury. Different metals have different reactivities with water and dilute acids.

━━━━━━━━━━━━━━━━━━━━━━━━━━

$\implies$ There are about 116 known elements. These elements of in divided into three main groups depending on their properties. They are:—

• Metals
• Non-Metals
• Metalloids

The elements which show the properties of both metals and non-metals are called metalloids, for example, antimony and arsenic.
