How big is a human cell in comparison to an atom?

Question

100 times bigger? 1,000 bigger? How many cells make up our body? How many atoms?

Answer 1

A typical atomic size is about 0.3 nanometers across. A typical animal cell is about 10 micrometers across. That's a factor of 33,000 times wider.

There are around approximately 40 trillion cells in the human body. There are approximately 7*10^27 atoms in the human body. That's 7,000,000,000,000,000,000,000,000,000 atoms.

Answer 2

Atom Size Comparison

Answer 3

Think of this:

An amino acid is made of at least 8 atoms.

A protein chain is made of at least 28 amino acids.

Cell tissue is made of hundreds if not thousands of protein chains.

So a cell is atleast several hundred thousand atoms.

Besides a cell is 1x10^-5 meters, while an atom is 5*10^-11 meters. That's 5 million times larger than an atom.

Answer 5

If a cell is as big as a baseball stadium, then an atom is about the size of this zero I'm about to type: 0

Namely, roughly 100,000 as wide. This is a very rough estimate though, because it depends on what atom and what cell you are talking about.

Answer 6

uhhh..........i just know cells are REALLY big in comparison to atoms. if it really matters to you, you could ask a scientist!!!! OR, you could count all the atoms yourself.
