Which of the following is true of an unstable nuclei? (Select All that apply)

• It's radioactive

• Weak nuclear force > Strong nuclear force

• Strong nuclear force > Weak nuclear force

• It fuses together with another nuclei

• It releases visible light

Under what conditions provide a stable nucleus?

• Having more than 83 protons

• Having more protons than neutrons

• Having way fewer protons than neutrons

• Having protons that are about equal too or fewer than the number of neutrons

• Having a very large nucleus

What is shown in this image?

• 3 different isotopes of the same element

• 3 different elements

• an alpha, beta and gamma particle

• 3 isotopes of 3 different elements

How do these carbon isotope differ from one another?

• number of neutrons

• number of electrons

• number of protons

• number of ions

What information can you extrapolate from the isotope notation written above? (Select All that apply)

• mass of 238

• mass of 94

• atomic number of 238

• atomic number 94

What is radioactivity?

• an unstable nuclei releasing particles and rays (energy) to regain stability

• a stable nuclei gaining particles and rays to create high energy

• an unstable nuclei gaining particles and rays (energy) to regain stability

• a stable nuclei releasing particles and rays to create high energy

How do chemical reactions differ from nuclear reactions?

• chemical reactions gain / lose / share valence electrons while nuclear reactions only deal with the nucleus

• chemical reactions form new substances while nuclear reactions do not

• chemical reactions are unpredictable while nuclear reactions are very predictable

• chemical reactions gain / lose / share valence electrons while nuclear reactions do not exist in nature
