How long is a hydrogen atom?
A hydrogen atom has a diameter of approximately 1.06×10−10 m 1.06 × 10 − 10 m , as defined by the diameter of the spherical electron cloud around the nucleus.
How much space does a billion atoms take up?
In other words, one billion atoms could line up across the diameter of the battery. The thickness of a sheet of paper is about 100,000 nanometers or 105 nm. A sheet of paper is about six orders of magnitude thicker than an atom. In this example, a stack of 1,000,000 atoms would be the same thickness as sheet of paper.
How much do a billion lead atoms weigh?
A billion lead atoms (1,000,000,000 atoms) weigh about 3 × 10-13 grams, a mass that is far too light to be weighed on even the world’s most sensitive balances.

Which of the following is the size of hydrogen atom?
A hydrogen atom has a diameter of 1. 06∗10−10m. The nucleus of the hydrogen atom has a diameter of approximately 2.
What does 1 million atoms weigh?

How many atoms would you have if you had 2.0 moles of atoms?
If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.
What is the size of a hydrogen atom in angstroms?
The unit of length convenient on the atomic scale is known as an angstrom and is. denoted by Å: 1 Å = 10–10 m. The size of a hydrogen atom is about 0.5 Å.
