Question

The size (diameter) of the hydrogen atom is all, except:

(a) 10^-10 m

(b) 1nm

(c) 10^-8 cm

(d) 0.1nm

Answer 1

Hi Sofia,

The diameter of a hydrogen atom is 0.1 nm.

This means that D is definitely not the answer for this problem here, because this is an All Except problem where we are looking for the wrong answer (if there is one).

The wrong answer here is B, because 1 nm is not the same as 0.1 nm, but A and C are the same as 0.1 nm.

10 ^(-10) m * (1 nm / 10 ^(-9) m) = 10 ^(-1) nm = 0.1 nm

10 ^(-8) cm * (1 nm / 10 ^(7) cm) = 10 ^(-1) nm = 0.1 nm

So the answer for this question should be B.

Hope this helps! Have a good day!
