the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

Can atomic mass increases be used to describe rows or columns in the periodic table?

Atomic mass increases primarily describe the trend across periods (rows) in the periodic table, as elements in the same row have increasing atomic numbers and generally higher atomic masses. In columns (groups), atomic mass can also increase, but the trend is less consistent due to varying electron configurations and isotopes. Therefore, while atomic mass can provide some insight into both rows and columns, it is more straightforwardly applicable to horizontal trends across periods.

How did they come up with the symbols for atomic mass and atomic number?

The symbol for atomic mass is "A," which stands for the mass number of an atom. The symbol for atomic number is "Z," which represents the number of protons in an atom's nucleus. These symbols were established by chemist Frederick Soddy in the early 20th century to help organize and describe information about elements and isotopes.
