  1. Atomic Structure Worksheet USE THIS TO HELP YOU!!!

  2. PROTONS- I need to know the number of protons….. • Do you have a periodic table of elements? If so, the number of protons is the same as the atomic number, the smaller number. • Do you know the atomic number? If so, then they are the same number. • Do you know the number of electrons? If so, then they are the same number.

  3. ELECTRONS- I need to know the number of electrons….. • Do you know the atomic number? If so, then they are the same number. • Do you know the number of protons? If so, then they are the same number!

  4. ATOMIC NUMBER- I need to know the atomic number….. • Do you have a periodic table of elements? If so, then find the number the periodic is organized by, and that is the atomic number. • Do you know the number of electrons? If so, then they are the same number. • Do you know the number of protons? If so, then they are the same number.

  5. ATOMIC MASS / WEIGHT- I need to know the atomic mass / weight… • Do you have a periodic table of elements? If so, find the largest number (number with the greatest value) and round it to the nearest whole number, if necessary. • Do you know the number of protons and neutrons? If so, add the number of protons and neutrons to get the atomic mass / weight. Number of Protons + Number of Neutrons ATOMIC MASS / WEIGHT

  6. NEUTRONS- I need to know the number of neutrons….. • Do you know the atomic mass / weight AND the number of protons? If so, subtract the number of protons from the atomic mass/ weight. ATOMIC MASS / WEIGHT -- NUMBER OF PROTONS NUMBER OF NEUTRONS
