| Element | # of Atoms |
|---|---|
| hydrogen | 4.22 x 10 27 |
| oxygen | 1.61 x 10 27 |
| carbon | 8.03 x 10 26 |
| nitrogen | 3.9 x 10 25 |
Where do our atoms go when you die?
When we die, our atoms will disassemble and move off to finds new uses elsewhere – as part of a leaf or other human being or a drop of dew. Atoms themselves, however go on practically forever.
How old are our atoms?
4.5 billion years
Are new atoms created?
Atoms cannot be created nor destroyed, and they are indestructible; they cannot be broken into smaller parts. This was based on the Law of Conservation of Mass. It was later learned that atoms can break into smaller parts. When atoms of different elements form compounds, they combine in a simple, whole number ratio.
Where did my atoms come from?
So the atoms on our bodies come from the pre-planetary cloud, which consisted in original hydrogen enriched by Popullation III and Popullation II explosions. Please note: due to chemical reactions, electrons in the atoms do not need to be the same they were while they were ejected by the stars, but the nucleus are.
Do atoms ever touch?
If “touching” is taken to mean that two atoms influence each other significantly, then atoms do indeed touch, but only when they get close enough. With 95% of the atom’s electron probability density contained in this mathematical surface, we could say that atoms do not touch until their 95% regions begin to overlap.
Do human cells regenerate every 7 years?
According to researchers, the body replaces itself with a largely new set of cells every seven years to 10 years, and some of our most important parts are revamped even more rapidly [sources: Stanford University, Northrup].
