“Our atoms in our body have embarked on an epic odyssey, with time spans from billions of years to mere centuries, all leading to you, all of you, witnesses of the universe.” So then it hits me. ...
Werk says tracking the flow of matter from the origin of the universe to present day, and understanding where the atoms that make up the air we breathe and water we drink is one of the fundamental problems in astrophysics. “It’s one of the holy grails of extra galactic cosmology,...

How many atoms are in the human body? Suzanne Bell, an analytical chemist at West Virginia University, estimates that a 150-pound human body contains about 6.5 octillion(that's 6,500,000,000,000,000,000,000,000,000) atoms. The vast majority of them are hydrogen (humans are almost entire...
If you know where a certain element sits in the table, and you know a little bit about the properties of the elements above, below, and either side, you can often figure out what the properties of that element will be.How do atoms make molecules and compounds? Atoms are a bit like ...
