Question
What is the standard-form estimate for the atomic radius of an atom?
Answer
The standard-form estimate for the atomic radius of an atom is 1 x 10^-10 m. This answer is tied to Size and mass of atoms and the objective: Recognise 1 x 10^-10 m as a standard-form estimate for atomic radius. This answer is tied to Size and mass of atoms and the objective: Recognise 1 x 10^-10 m as a standard-form estimate for atomic radius.
Explanation
This answer is strong because it directly addresses the question about the atomic radius in standard form, demonstrating understanding of the size of atoms. The question tests recall of a specific fact related to atomic structure. It belongs to Size and mass of atoms in A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes, so it should not be merged with nearby Chemistry concepts.

Common mistake
Misunderstanding Standard Form
Students often confuse 1 x 10^-10 m with 1 x 10^-9 m when estimating atomic radius.
Remember that 1 x 10^-10 m is the correct standard-form estimate for atomic radius, which is much smaller than 1 x 10^-9 m.
