DON’T COPY:
Write a list of steps that explains how to check to see if the
number of PROTONS, NEUTRONS AND ELECTRONS IS
CORRECT.
At least 3 numbered steps. COMPLETE SENTENCES.
Include a periodic table square to use to illustrate your steps.
Label “Atomic Number” and “Mass number”

What’s Inside an Atom
A) # below symbol = atomic number
Atomic # = # of protons(reds)
B. # above the symbol = mass number
Mass number =particles inside the nucleus (reds and
blues)
C. Sometimes there is more than one mass numberAtoms can have different numbers of neutrons (blues)
These are called isotopes.
D) What about yellows?

HYPOTHESIS:
Rutherford expected the positively charged alpha
particles to pass through the gold atom
Why did so few alpha particles hit the nucleus?
Why did they bounce off? (2 reasons)

Why did so many alpha particles miss the nucleus?
Because the atom is mostly….
