BIO BEYOND UNIT 6 ENERGY CHALLENGE
PHOTOSYNTHESIS EXAMPREP 2026
COMPLETE QUESTIONS AND CORRECT
ANSWERS
⩥ Which scenario below do you think is most likely for this
experiment's results? Make a hypothesis. Answer: any answer
⩥ Why did this surprise Rutherford? Answer: Thomson's model of the
atom had a diffuse positive charge, so the particles should not have been
deflected very far
⩥ How was Rutherford's model different from his mentor, Thomson's?
Answer: Rutherford's model had a small, dense, positive nucleus
⩥ What differences does Bohr's model have compared to Rutherford's?
Select all that apply: Answer: Distinct energy levels for electrons
Distinct orbits for electrons
⩥ How is Schrödinger's model different from Bohr's? Answer: Electrons
don't have orbits but have volumes they may occupy
, ⩥ Where is most of the mass in an atom located? Answer: Nucleus
⩥ What makes up most of the volume of an atom? Answer: Empty space
⩥ Connect the name of the scientist to their contribution to the modern
model of atomic structure. Answer: Next 6
⩥ Bohr Answer: Electrons in orbits by energy levels
⩥ Rutherford Answer: Initial concept of nucleus
⩥ Thomson Answer: Initial concept of electrons
⩥ Schrodinger Answer: Electrons in clouds
⩥ Chadwick Answer: initial concept of protons and neurons
⩥ Democritus Answer: Initial concept of atom
⩥ Fill in the table below to describe the characteristics and location of
the particles that make up an atom. Answer: left to right and top to
bottom
