Question

Many atomic dimensions are expressed in angstroms (A). (1A = 1 x 10-8cm). What is the angstrom equal to in terms of the SI units nanometer (nm) and picometer (pm)? Report your answers in scientific notation.

Answer 1

1 Å = 1.0 × 10⁻¹ nm

1 Å = 1.0 × 10² pm

Step-by-step explanation:

Angstrom is the unit of the length which is equal to one ten-billionth of the metre or 10⁻¹⁰ m. It is represented by the symbol is Å .

Angstrom is not part of SI system of the units, but it is considered as a part of metric system.

Angstrom is used often in natural sciences as well as technology in order to express the sizes of atoms / molecules, and the lengths of the chemical bonds, etc.

1 Å = 10⁻¹⁰ m

1 nm = 10⁻⁹ m

1 pm = 10⁻¹² m

So,

1 Å = 1.0 × 10⁻¹ nm

1 Å = 1.0 × 10² pm
