  1. Birth of elements Homework and review Questions

  2. Q1 The process in which smaller atomic nuclei combine into larger atomic nuclei is known as • gravitational attraction. • nuclear fusion. • nuclear fission • subjugation.

  3. Q2 All of the gold found on Earth was originally created in • Our Sun • In a star about the size of our Sun • In a star much larger than our Sun • In supernovas that occurred before our creation of our sun

  4. Q3 During Nucleosynthesis • the nuclei of 2 or more atoms are pushed together • the nucleus of an atom is split apart • really needs the force of Owls to make it happen • the nucleus of an atom adds electrons or neutrons

  5. Q4 Describe what happens during nuclear fission

  6. Q5 Describe what happens during nuclear fusion.

  7. Q6 What makes a nuclear reaction different from a chemical reaction?

  8. Q7 This is important in determining the stability of a nucleus. • The proton to electron ratio (B) The electron to neutron ratio (C) The neutron to proton ratio (D) The valence electron to core electron ratio

  9. Q8 When an atom splits into smaller atoms, it is called • a chemical reaction (B) a compound (C) nuclear fission (D) nuclear fusion

  10. Q9 When two elements combine to create a new element, it is called • a chemical reaction (B) a compound (C) nuclear fission (D) nuclear fusion

  11. Q10 What elements are formed in cool stars? • H and He (B) up to Fe (C) beyond Fe to Bi (D) all of them

  12. Q11 When one element breaks apart to create two new elements, it is called • a chemical reaction (B) a compound (C) nuclear fission (D) nuclear fusion
