Answer 3

guyz pls reply somethin

Answer 4

idk what you're asking.. the atomic number and mass are two different things... the periodic table I have shows the number and weight (and much more)

Answer 5

to find atomic mass, round atomic weight to nearest whole number

Answer 6

the atomic number represent the number of protons in the atom and correlate with the number in the periodic table. For Example: H atomic number is 1 has only one proton, He atomic number is 2 has two protons in the nucleus. The atomic mass is calculated as the sum of the mass of the protons plus the mass of the neutrons in the nucleus of an element atom. In the case of Hydrogen in the nucleus has only one proton and no neutron so the mass is 1 amu (atoms mass unit), in the case of Helium has 2 protons and also has 2 neutrons so the atomic mas for Helium is 4 amu and its atomic number is 2.
If you are interested in any particular element let me know. Also the atomic mass is in the periodic table but is expressed has the average mass of the natural abundance of the different isotopes of the element (a little more complicated for your question.
