The probe passing over an atom allows scientists to gather information about the atom's structure, composition, and behavior. This can help us understand the properties and interactions of atoms, which are the building blocks of all matter.
The size of an atom is typically measured in picometers (pm), which is one trillionth of a meter. 3.20×10^2 nm is equal to 3.20×10^5 pm, which is considered to be a relatively large atom. Most atoms have a diameter of around 1-2 pm.
The height of an atom is usually measured using a scanning probe microscope, which uses a sharp probe to scan the surface of the atom. The height is determined by the distance between the probe and the surface of the atom.
The "nm" in 3.20×10^2 nm represents nanometers, which is a unit of measurement equal to one billionth of a meter. This is a commonly used unit when measuring the size of atoms and other particles.
The height of an atom does not directly affect its properties. However, the size and arrangement of atoms can influence the physical and chemical properties of a substance. For example, smaller atoms tend to have stronger intermolecular forces, which can affect the melting and boiling points of a substance.
