Answer 1

The Bohr radius of a hydrogen atom is given as \( 0.0000000000529 \). To express this in scientific notation, we can rewrite it as:

• First, we can write it as \( 5.29 \times 10^{-11} \).

So the correct response is:

5.29 x 10^−11

Answer 2

Of course it does not say if that is in meters, miles or foot lengths. I suppose it is reasonable to assume it means meters.

Answer 3

Yes, in the context of atomic physics and quantum mechanics, the Bohr radius is typically expressed in meters. The value \( 5.29 \times 10^{-11} \) meters is indeed a common representation of the Bohr radius for a hydrogen atom. If you have any further questions or need more information, feel free to ask!
