Self-study tips-1

Please refer to textbook P106-P107

A. What are the physical properties of pure diamond? What uses?

B. What are the physical properties of graphite? What uses? What properties are reflected in these uses?

1. Carbon element

1. Diamond - noble and gorgeous carbon element

Have you seen diamond in your daily life? What are its properties?

nature

It is a colorless, transparent, regular octahedral-shaped solid with a high refractive index and strong dispersion.

After careful consideration, it becomes an ornament - a diamond.

The hardest substance found in nature.

Scribe glass, cut marble, process hard metal, and drill bits into hard rock formations.

2. Graphite - an ordinary and versatile carbon substance

⑴ Graphite has a slippery feel and graphite is very soft.

How do you feel after grinding your fingers on the pencil lead a few times?

What properties does this indicate about graphite?

What is the use of this property? Can be used as lubricant.

Compare the differences between carbon and carbon:

"Carbon" is the name of the element and is the general name for a class of atoms with a nuclear charge of 6. For example: carbon element, carbon element, carbon-containing compounds, carbon monoxide. (Cannot use "charcoal" here)

"Charcoal" means a certain substance composed of carbon elements - charcoal, activated carbon, coke, carbon black, etc.

What is the C60 made of? Is it the same composition as diamond and graphite? What aspects of C60 are being researched for?

C60 is made up of C60 molecules. Different from diamond and graphite, diamond and graphite are composed of carbon atoms; research on the use of C60 in materials science, superconductors, etc. is ongoing.

Summary

⒈Different elements can make up different substances; the same element can also make up different substances.

⒉Charcoal and activated carbon have adsorption properties.

⒊Chemistry is a science that is very closely related to life; chemistry uses experimental exploration as a means to continue to develop, and new chemical technologies make our world more colorful.

⒋All external manifestations of matter are determined by its internal factors. The structure of a substance determines its properties; its properties determine its use.
