The question is:
The radius of an atom of element X is 1.2 x 10-10(10 to the power of -10)
The radius of the centre of the atom is 1/10000 the radius of an atom.
Calculate the radius of the centre of the atom of element X
Give your answer in standard form

You’re given the radius of the of the atom, and told the radius of the centre is 1/10000 of this. So you’re calculating 1/10000 of 1.2 x 10^-10
All you would have to do is divide 1.2 x 10^-10 by 10000
So the standard form answer would move 4 place values to the left
the standard form answer would be decreased by 4
And the final answer is 1.2 x 10^-14
Does this about right?
