What is the term used to describe the range of neutron to proton ratios that result in a stable nucleus?

• Electromagnetic force

• Magic numbers

• Belt/Band of stability

• Unstable nuclei

Which force is responsible for holding the nucleus together?

• Electromagnetic force

• Strong nuclear force

• Gravitational force

• Weak nuclear force

What are nucleons?

• Electrons and protons

• Neutrons and electrons

• Protons and neutrons

• Electrons and neutrons

What is a nuclide?

• A type of chemical bond

• A specific isotope of an element

• A molecule with a high atomic number

• A stable electron configuration

Which type of particle in an atom has a positive charge?

• Neutrons

• Electrons

• Protons

• Photons

What charge do neutrons have?

• Positive

• Negative

• Neutral

• Variable

Which particle in an atom has a negative charge?

• Protons

• Neutrons

• Electrons

• Positrons

What are the particles called that make up most of an atom's mass?

• Electrons

• Neutrons and protons

• Electrons and protons

• Neutrons and electrons

Where are electrons found in an atom?

• Inside the nucleus

• In energy orbitals around the nucleus

• Mixed with protons

• In the center of the atom

What is the role of the strong nuclear force within the nucleus?

• It binds protons and neutrons together.

• It causes the repulsion between protons.

• It only affects electrons.

• It weakens the nucleus.
