Angstrom?

[Tyra Nguyen 4H]

What is an Angstrom and how is it applied in the lab?

[Kate Chow 4H]

An angstrom is just a unit of length (think meter as another example) that is equal to 1*10^-10 m or 0.1 nm. I know Dr. Lavelle mentioned that angstroms are used to express wavelengths, so they are probably applied in lab in that way as well.

It's important to remember that angstrom is only a measure of distance (meters), so be careful not to call 1 x 10^-10 an angstrom, because it could be 1 x 10^-10 liters or moles or anything, and angstrom wouldn't fit in anything other than meters.

[Ricardo Martin 1J]

An angstrom is equivalent to 1x10^-10 m and Dr. Lavelle stated that it would be common to find wavelengths to the ^-10m, therefore, the angstrom is used for convenience in writing these lengths.

[Dong Hyun Lee 4E]

An angstrom is just another unit name for 10^10 meters. So use this if your answer is in meters and is above this amount for a reasonable unit. It's like measuring a road as you would'nt give the distance in centimeters unless specifically asked to for a 4000 m stretch of road.

An Angstrom is a short hand way to show the approximate distance of the diameter of 1 hydrogen atom. It is used primarily to show wavelengths and intermolecular distances.

You'll commonly see it written as Å in this class for exams, etc, and it is used to measure the size of atoms/molecules, the length of chemical bonds, or the wavelengths of electrochem radiation. It is equivalent to 1.0 × 10-10 meters, but its not an SI unit. For example, hydrogen is about 0.5 Å, while chlorine and sulfur are 1 Å.

[Jake Gordon 1A]

An angstrom(Å) is a non- SI unit equal to 10 to the -10th meters. This is a valuable unit because it is around the value of wavelengths of light and interatomic distances (ex. diameter of a hydrogen atom).

[Hannah Padilla 1H]

An Angstrom is the diameter of 1 Hydrogen atom, or 10^-10. We use this, because SI units go by 3s.
