Nuclear fusion occurs where?
The core of a star

Why do protons and neutrons make up almost all of an atom's mass, even though the nucleus is very small?
Protons and neutrons are much heavier than electrons.

In Rutherford's experiment, most alpha particles passes straight through the gold foil but a small number bounced back. Based on this evidence, what was Rutherford able to conclude?
Atoms are mostly empty space with a small dense nucleus.

In the simplified hydrogen fusion model, four hydrogen atoms combine to form one helium atom. What else is released?
Energy (heat & light)

A student claims that when an atom gains one neutron, its become a different element. Is this student's claim correct? Explain.
No, neutrons are only responsible for changing the mass of an atom. Changing the number of neutrons would produce different isotopes of the atom. The only way to change the element is to change the number of protons.

What must be true in order to have a neutral atom?
It has to have the same number of protons and electrons

Two neutral atoms each have 17 protons. Atom A has 18 neutrons and Atom B has 20 neutrons. Identify their element, mass numbers, and whether they are isotopes.
Both are chlorine. Mass numbers 35 and 37. They are isotopes because they have the same number of protons but different numbers of neutrons.

One Helium atom and one Carbon atom are fused together to form Oxygen. What is the change in mass due to this fusion reaction?
16.00 - 16.01 = -0.01

A scientist observes that a star's core contains less hydrogen and more helium as it ages. Explain how nuclear fusion causes both of these changes, and why the process releases energy.
Nuclear fusion combines hydrogen nuclei to form helium. As hydrogen is used, its amount decreases while helium increases. Some of the starting mass is converted into energy, which is released as light and heat.
