If atoms are 99,9% emptiness, how can they keep things together ? Like, if my skin is 99,9% emptiness, why is it able to keep blood and organs in it ?
In: Chemistry
Regarding your second question: the thing that noone seems to have mentioned is the scale of things here. The average number of atoms in each cell is estimated around 100 TRILLION. Thats each individual blood cell, or one of the hundreds of millions of cells that make up each of your organs. Asking how skin can contain blood is akin to asking how a chainlink fence can contain a dog, but the dog is millions of times larger than the holes in the fence
Its hard to eli5 atoms and how they interact with each other but theres some pretty good answers here so not gonna touch that one
