A. 0.22 x 10^-9 m
B. 2.2 x 10^-10 m ***
C. 2.2 x 10^-9 m
D. 22 x 10^-11 m
I'm not sure. Can someone please check? Thank you!! I need someone to check just really quick thank you so much
Yes.
You're correct! The diameter of a carbon atom, 0.00000000022 m, expressed in scientific notation is 2.2 x 10^-10 m, which corresponds to option B. Well done!
To express the diameter of a carbon atom, 0.00000000022 m, in scientific notation, we need to write it in the form of A × 10^B, where A is a number between 1 and 10, and B is an integer.
Starting with the given diameter, we can write it as:
0.00000000022 m = 2.2 × 10^-10 m
Therefore, the correct answer is B. 2.2 x 10^-10 m.
