Molecules are pure substances that are made up of two or more atoms of one or more elements linked together by shared electrons. Molecules are also found in elements and compounds. One sheet of graphene is a very small amount, which can not be seen (or 1 atom thick) A compound is also a pure substance and is made up of atoms of two or more elements that are chemically combined. When a compound forms, elements join in a particullar ratio according to their masses. (example: water-1g in hydrogen: 8g in oxygen)

How does the conductivity of graphene compare to that of silver?

Graphene has higher conductivity than silver.


What are the key differences between graphene and graphene oxide in terms of their properties and applications?

Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, known for its exceptional strength and conductivity. Graphene oxide is graphene that has been chemically modified with oxygen-containing functional groups, making it easier to disperse in solvents. Graphene is mainly used in electronics and materials science, while graphene oxide is often used in biomedical applications due to its biocompatibility and water solubility.


How can one make graphene at home?

It is not recommended to make graphene at home due to the complex and potentially dangerous process involved. Graphene is typically produced using specialized equipment and techniques in a controlled laboratory setting. Attempting to make graphene at home without proper knowledge and equipment can be hazardous.


How does graphene form?

Graphene forms through a process called mechanical exfoliation, where layers are peeled off from graphite using adhesive tape. Another method is chemical vapor deposition, where a thin layer of graphene is grown on a metal substrate using gases like methane. Graphene can also be produced using techniques like liquid-phase exfoliation or epitaxial growth.


Why is graphene strong?

Graphene is strong because its carbon atoms are arranged in a tightly-packed hexagonal lattice that provides a stable structure. This unique arrangement allows graphene to efficiently distribute and absorb mechanical stress, making it incredibly strong for its size. Additionally, the strong covalent bonds between carbon atoms in graphene contribute to its exceptional mechanical properties.

What is a graphene filter?

A graphene filter is a type of filter that uses graphene-based materials to capture and remove impurities from a fluid or gas. Graphene's unique properties, such as its high surface area and strength, make it an effective filtration material for applications like water purification, air filtration, and gas separation. Graphene filters are known for their efficiency, durability, and ability to remove even small particles or contaminants.


Is graphene is hardest thing in the world?

Graphene is not the hardest material in the world; it is actually one of the strongest and lightest materials known. Graphene's strength comes from its unique structure, where carbon atoms are arranged in a single layer. While graphene has impressive strength-to-weight ratio, there are harder materials like diamond or aggregated diamond nanorods.

What is the most elastic substance in the world?

Graphene is considered one of the most elastic substances in the world. It is a two-dimensional material composed of a single layer of carbon atoms arranged in a hexagonal lattice structure, known for its exceptional strength, flexibility, and elasticity.


Can you make your own graphene from pencils?

While it is technically possible to extract graphene from pencils using a process called exfoliation, it is not very efficient or practical for producing high-quality graphene. Laboratory techniques and equipment are typically used to produce graphene on a larger scale for commercial applications.
