The scientific notation for the given information is 1 × [tex]10^{-10}[/tex]. Thus, one angstrom is written as 1 × [tex]10^{-10}[/tex] and denoted by A°.
Scientific notation is used to write very large numbers or very small numbers in a simple way that is easy to understand and easy for calculate.
A number is written in scientific notation as follows:
Scientific notation: m × [tex]10^n[/tex]
where m is the absolute value of the number or a decimal number and n is the power and 10 is the base.
The given information is,
One Angstrom = ten billionths part of a meter
Since ten billion = [tex]10^{10}[/tex]
So, ten billionth part of a meter = 1 ×1/[tex]10^{10}[/tex] = 1 × [tex]10^{-10}[/tex].
therefore, the scientific notation for one Angstrom is 1 × [tex]10^{-10}[/tex].
