Metals and Non-Metals Class 10 notes

Metals and Nonmetals Class 10 Notes There are currently 150 known chemical elements with similarities and differences in their properties. All elements can be divided into two main groups based on their properties: metallic and non-metallic. In our daily life, we use both metals and non-metals. We also use a number of metallic and non-metallic compounds. Metals metals are elements that conduct heat and electricity and are malleable and malleable. The metal was also shiny and had a strong focus and tone. Examples of metals include iron, aluminum, copper, silver, gold, platinum, zinc, lead and mercury. If you hit a chunk of iron with a hammer four or five times, you'll find that the metal strip of aluminum turns into a thin sheet of aluminum without breaking. And aluminum metal is said to exhibit malleability or paintability. Yield is the ability of a metal to be hammered into a thin sheet. Formability is an important property of metals. Most metals are malleable. Gold and...
