Pre-Lab Questions
Please answer these questions before gathering materials for your lab.
1. Choose an element with an atomic number between 5 and 13. This is the
element you will be making with gummy bears and gumdrops. Fill in the
information below for the element.
a. Element Name
b. Atomic Number
c. Atomic Symbol
d. Atomic Mass
e. Number of Protons
f. Number of Electrons
g. Number of Neutrons
2. Draw a Bohr model of this atom below. Make sure to show the electrons in
their appropriate orbitals. Indicate protons with + symbols, neutrons with =,
and electrons with -.
