so that we can easy to know the measuring mass of an atom
.0000000001
1.1 to 3.5 *10^-10 metres.
The Vander Waal radius ranges from 1.2*10^-10 to 3.5*10^-10 metres.
As far as we know, we only use scientific notation here on Earth, for the computing of very large numbers (like the distance between planets) or very small numbers (like the radius of a hydrogen atom).
The diameter of a carbon atom, 0.000 000 000 154 m, can be expressed in scientific notation as (1.54 \times 10^{-10}) m. This is achieved by moving the decimal point ten places to the right, which corresponds to the negative exponent of ten.

To represent a really big or really small amount Like the size of a single atom
1.06*10-7
scientist accepted bohr's model as a useful explanation (apex)
There are many alternatives; for example (denoting the element atom by A):A-mass number; e.g U-235, orAmass number, oratomic numberAmass number; , 92U235
The mass of the atom in scientific notation can be expressed as (1.12 \times 10^{-15}) grams. Therefore, the entry in the physicist's journal would be written as (E = 1.12 \times 10^{-15}) grams. This notation allows for easier handling and communication of extremely small values.
1.06x10-7 mm or 1.06x10-10 m
1.64 nm 1.64 nanometers or 1.64 x 10-9m
it is an atom
