The atomic radius of a hydrogen atom is:
10⁻¹⁰ m
10⁻⁷ m
10⁻⁸ m
10⁻⁹ m
10⁻¹⁰ m
Atomic radius of a hydrogen atom and standard atomic scales
Bohr radius: a0≈0.53×10−10 m
Atomic radius scale: 10−10 m (1 Ångström)
Nuclear radius scale: ∼10−15 m
Bohr Radius of Hydrogen
In Bohr's model, the radius of the ground state of a hydrogen atom (n=1) is given by: a0=mee24πε0ℏ2≈0.529×10−10 m=5.3×10−11 m
Order of Magnitude
The standard atomic radius is commonly expressed in angstroms (1 A˚=10−10 m). Thus, the order of magnitude is 10−10 m.
Atomic radius of hydrogen is 10⁻¹⁰ m.
10⁻¹⁰ m
