More than anything else, we are made of empty space. If the nucleus of a hydrogen atom was the size of a basketball then the electron that orbits it would be about about 3km away (about half the height of Mount Kilimanjaro). Hydrogen is the most common element in the universe and makes up 10% of the human body. It's the third most plentiful element in the human body, behind oxygen (65%) and carbon (18%). . . . #Halifax #NovaScotia #handdrawn #micronpen #rotringartpen #ink #instaart #drawing #art #etchr #etchrsketchbookhotpress #padair #applepencil #photoshopipad (at Halifax, Nova Scotia) https://www.instagram.com/p/B9U59kKny14/?igshid=5k6etmmjomtf
