What is the atomic mass on the periodic table?
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
Are the sum of two periodic functions always periodic?
yes
