Pencil leads and diamonds are chemically identical; the difference is in the crystal structure. Martha Foley and Dr. … May 03, 2018 — Pencil leads and diamonds are chemically identical; the difference is in the crystal structure.
Can pencil lead make a diamond?
In graphite, carbon atoms are arranged in planar sheets that can easily glide against each other. This structure makes the material very soft and it can be used in products such as pencil lead. … One way to turn graphite into diamond is by applying pressure.
Why do diamonds and pencil lead have different properties?
In diamond, each carbon atom is bonded to four other carbon atoms, forming a rigid structure that makes diamond very hard. In graphite, each carbon atom is bonded to three other carbon atoms, and the atoms forms layers that are only weakly bonded together. This makes graphite soft and slippery.
What is the difference between of diamond and graphite?
Diamond and graphite are allotropes of carbon. These have different chemical and physical properties. The main difference between diamond and graphite is that diamond is made out of sp3 hybridized carbon atoms whereas graphite is made out of sp2 hybridized carbon atoms.
Can you write with diamond?
It is typically about 99.95 percent carbon. … Another mineral, graphite, also contains only carbon, but its formation process and crystal structure are very different. The result is that graphite is so soft that you can write with it, while diamond is so hard that you can only scratch it with another diamond.
Can you melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. … The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
Can I grow diamonds at home?
The gas mixture is heated to very high temperatures in the microwave to produce a plasma ball, and inside this, the gas breaks down and the carbon atoms crystallise and accumulate on the diamond seed, causing it to grow. …
