The size of a hydrogen atom is about 1.2×10^−10 m across. The size of an oxygen atom is 0.000000000152 m across. What is the difference between the sizes of these atoms in scientific notation?(1 point)

1 answer

The difference between the sizes of these atoms can be found by subtracting the size of the hydrogen atom from the size of the oxygen atom.

0.000000000152 - 1.2×10^−10

To put these values in scientific notation, we can write:

1.52×10^−10 - 1.2×10^−10

Subtracting the two values, we get:

0.32×10^−10

Finally, we can also express this in scientific notation as:

3.2×10^−11

Therefore, the difference between the sizes of these atoms in scientific notation is 3.2×10^−11.
