Question

C1 Progress quiz: Atomic structure 2 - test

4 The atomic radius of a silicon atom is 1.1 x 10-10 m. Calculate its atomic radius in
nanometres.
O
11 nm
o
0.011 nm
0.11 nm
1.1 nm​

Answer 1

0.11 nm

Step-by-step explanation:

1.1 x 10-10 m

The goal is to convert the atomic radius from meters (m) to nanometres (nm). We do this by multiplying the value by 10^9.

This is given as;

`1.1 * 10^(-10) * 10^(9)\\1.1 * 10^(-10 + 9)\\1.1 * 10^(-1)\\0.11`
