How do you read chemical symbols?
Each element is represented by its atomic symbol in the Periodic Table – e.g. H for hydrogen, Ca for calcium. If more than one atom of a particular element is present, then it’s indicated by a number in subscript after the atomic symbol — for example, H 2 O means there are 2 atoms of hydrogen and one of oxygen.
What can represent an atom?
An atom consists of a small, positively charged nucleus surrounded by electrons . The nucleus contains protons and neutrons; its diameter is about 100,000 times smaller than that of the atom. The mass of one atom is usually expressed in atomic mass units (amu), which is referred to as the atomic mass.

Are humans made of atoms?
About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life. ... The very heavy elements in you were made in exploding stars. The size of an atom is governed by the average location of its electrons.
Do atoms take up space?
In reality, atoms do not contain any empty space . Rather, they are filled completely with spread-out electrons, making the shrinking of atoms impossible.

Are atoms alive? A: This is a great philosophical question and the answer all depends on how you define “alive.” We don’t usually say something is alive unless it can at least grow or reproduce or metabolize. While atoms can join together to form beings that do these things, individual atoms do not.
