Shorthand notation is also known as scientific notation. In scientific notation, we write a number between 1 and 10, followed by a multiplication sign, and the power of 10 to which the number is raised. Here, the diameter of the hydrogen atom is 0.000,000,000,11 m.

To convert this to scientific notation, we need to move the decimal point 10 places to the right to make the number between 1 and 10. This gives us 1.1. The decimal point has now moved 10 places to the right, so we write 10^-10 (because we moved the decimal point 10 places to the right, it's -10). So the shorthand notation is 1.1 × 10^-10 m.

Therefore, the best choice is B, 1.1 × 10^-10 m.
