WebTo the left of the symbol we find the atomic mass (A) at the upper corner, and the atomic number (Z) at the lower corner. Examples: 1H 1 C 12 6 Na 23 11 A Symbol Z Electron trade constitutes the currency of chemical reactions. The number of electrons in a neutral atom (that is, the atomic number) gives the element its unique identity.
