Question 7
If an atom has a neutral charge, then
there are an equal amount of
A. Protons and Neutrons
B. Protons and Electrons
C. Neutrons and Electrons
D. Ions and Half-life

Protons give off a positive charge and
electrons a negative charge. To get a
neutral charge you would need equal
amounts.

C. Protons: 92 Neutrons: 162
D. Protons: 92 Neutrons: 178
Answer to Question 9
“Little Boy” the atomic bomb dropped on
Nagasaki used uranium-235. How many
protons and neutrons does it have?
The answer is B. Protons: 92 Neutrons:
143. Uranium-235 is an isotope.
Isotopes are elements with same # of
protons, different # of neutrons. (23592) to get # of neutrons

The atomic mass of a atom is the sum of
its protons, neutrons and electrons.
Isotopes do NOT have the same atomic
mass as the original element. True or
False?
The answer is true. The atomic mass
would be different due to the different
amount of neutrons in the atom.
