Candy Atoms Lab
Do not touch/eat items until instructed to do so…
Review:
1) How do you determine the number of protons in an atom?
2) How do you determine the number of electrons in an atom?
3) How do you determine the number of neutrons in an atom?
4) If an atom has 3 protons, what type of atom/element is it? Why?
Modeling an Atom:
Using the periodic table, draw what a Helium (He) atom would look like below:
(Show A=P=E M-A=N work here)
□protons □neutrons □electrons
Lab Activity:
Now choose a different element from the table (1-10):
Draw the element box from P. Table
