Lab 03 – Sub-atomic Particles
Introduction
Type an introduction about sub-atomic particles and the models of the atom. DO NOT forget to delete these
instructions.
Objective
Use M&M candies to represent sub-atomic particles, and arrange them to make a Bohr model of the atom.
Materials
Periodic Table, 3 colors of M&M candies, a copy of the blank Bohr model of the atom
Procedure
Summarize the procedure IN YOUR OWN WORDS. DELETE these instructions before printing your final lab
report.

Conclusions
TYPE YOUR CONCLUSION BELOW IN PARAGRAPH FORM. You MUST address all 3 questions, using examples
from the lab. DO NOT FORGET to spell/grammar check and PROOFREAD your final report. DELETE these
instructions and the questions.
1. The overall charge of an atom’s nucleus is positive? Why?
2. Atoms at ground state are neutral. How is this possible, if the nucleus is positive?
3. Is there a pattern(s) to the way in which the periodic table is organized? Explain in terms of sub-atomic
particles, and using examples from this lab.
