Why is the krypton atomic mass not determined?
The relative atomic mass is 83.798. So where did you get that it is not determined.
How do you get the atomic mass and and atomic number?
it is simple. all you need to do is look in the periodic table the numbers above and under the letter.Atomic number is determined from the number of protons in the nucleus. Atomic mass is determined from the number of protons AND neutrons in the nucleus. Since elements have multiple isotopes with differing numbers of neutrons, the atomic mass reported on periodic charts is usually the average atomic mass. As the first person who answered this question pointed out, you can usually find the atomic number by looking for a number above the atomic symbol for the element in the the table (H for hydrogen, C for carbon, Fe for Iron, Au for gold, etc.). Sometimes the number will be below the symbol but in bold font. When the periodic table gives an atomic mass, it is usually given under the atomic symbol and is almost always some kind of decimal number that is always greater than the atomic number, for example: Carbon has an atomic number of 6and an atomic mass of 12.0107 amu.
