What is the Difference Between Graphite and Lead?

The main difference between graphite and lead lies in their composition, properties, and uses. Here are the key differences between the two:

• Composition: Graphite is a form of pure carbon arranged in hexagonal layers, while lead is a mixture of graphite and clay.
• Primary Color: Graphite is typically black or dark gray, whereas lead comes in various shades of gray, including light gray.
• Hardness: Graphite is relatively soft and easily marked, while lead varies in hardness, ranging from very soft (e.g., 6B) to very hard (e.g., 9H).
• Toxicity: Graphite is nontoxic and highly stable, whereas lead is toxic and unstable.
• Uses: Graphite is commonly used in pencils, lubricants, and batteries, while lead is used in construction, batteries, and radiation protection.

In the past, pencils were made with lead, but modern pencils do not contain lead at all. Instead, they are made of graphite, which is safer and non-toxic.

Comparative Table: Graphite vs Lead

Here is a table highlighting the differences between graphite and lead:

Graphite is a soft, black, lustrous form of carbon that is nontoxic and highly stable, while lead is a heavy metal that is toxic and unstable. In the past, pencils were made with lead, but modern pencils do not have lead at all. They are now made of graphite, which is safe and a form of carbon. Graphite is ideal for sketching and shading due to its softness and darkness, while lead is harder and lighter, making it better for writing and drawing fine lines.
