The empirical covalent radius is cca. 25 pm, after Slater (the diameter is 50 pm).
The van der Waals radius for hydrogen is 120 pm, meaning a diameter of 240 pm.

Is atomic mass and atomic diameter the same thing?
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
What is the diameter of a tealight candle?
40mm diameter and 17mm tall (average tealight)
What is a protons relative size?
About a hundred trillion atoms can fit in the period at the end of this sentence. A proton is smaller than that.
What is the proportion of volume of proton to the volume of hydrogen atom?
The diameter of proton is 1*10 raised to the minus power of 15 meter. The diameter of hydrogen atom is 1* 10 raised to the power of minus 10 meter. The formula for volume of spere is 4/3*22/7*r raised to 3. From this you get that volume of the hydrogen atom is approximately 4,000,000,000,000,000 times more than that of proton. That means most of the atom is empty space.
What is a positively charged subatomic paricle?
The proton is a positively charged subatomic particle
How much bigger is a hydrogen atom than a proton?
A hydrogen atom has a diameter of about 60 picometers while a proton has a diameter of 1.75 femotometers. So a hydrogen atom's diameter is about 35,000 times that of a proton.
Is the proton smaller than the electron?
Actually every proton has different size in different nucleus. But in general, Proton, 1x10-15 m or "a diameter of approximately one-millionth of a nanometer". The electron, the diameter is less than 1x10-18 m. Likewise, The diameter of an electron is less than 1/1000 the diameter of a proton.
What is the ratio of the diameter of a hydrogen atom to the diameter of a proton?
That ratio is about 53,000.
What is the atom with the smallest diameter?
A hydrogen atom has the smallest diameter because there is only one proton and neutron.
What is the diameter of a proton in scientific notation?
They're having some trouble nailing down the diameter of a proton. It's somewhere around 8.5 x 10^-16 meters.
If a proton was 1cm across how big would the atom be?
The answer for a hydrogen atom would be about 100 meters across a proton is about 1/10,000 th of the diameter of a hydrogen atom.
Using the mass of the proton 1.0073amu and assuming its diameter is 1.010-15 m calculate the density of a proton in gcm3?
3.2 x 10^15 g/cm^3
How many miles in diameter is an average dwarf galaxy?
An average dwarf galaxy is small in diameter.
Is atomic mass and atomic diameter the same thing?
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
What is the average diameter of a protogalaxy?
About 100 light-years in diameter.
What is the average transverse diameter of a human heart?
it is 32cm in diameter
What diameter is the average adult airway?
The average diameter of the adult windpipe (or trachea) is 2.5cm (1 inch).
