The size difference between the hydrogen atom and the oxygen atom can be calculated by subtracting the size of the hydrogen atom from the size of the oxygen atom:
0.00000000152m - 1.2 x 10^-10m = 0.00000000152m - 0.00000000012m = 0.00000000140m
This size difference can be expressed in scientific notation as 1.40 x 10^-9m.
The size of a hydrogen atom is about 1.2 times 10^-10m across. The size of an oxygen atom is 0.00000000152m across. What is the difference between the sizes of these atoms in scientific in scientific notation?
