1. FORMATION OF LIGHT ELEMENTS PHYSICAL SCIENCE Week 1 RJLA

2. TARGETS explain stellar nucleosynthesis; describe the different stages of life cycle of stars; cite the different heavy elements formed in each stages of star cycle; describe how heavier elements formed during stellar nucleosynthesis and evolution.

3. FACT OR BLUFF Read and analyze the following statements. Choose FACT if the statement is TRUE and BLUFF if the statement is false. DEFEND your answer

4. TRUE ELEMENTS ARE MADE OF SUB ATOMIC PARTICLES CALLED PROTON, NEUTRON AND ELECTRONS

5. FALSE The identity of an element depends on how many neutron it has

6. TRUE LITHIUM IS ONE OF THE ELEMENTS FORMED DURING THE BIG BANG NUCLEOSYTHESIS

7. TRUE Nucleosysnthesis combines nucleons (proton and neutron) to form Elements

8. FALSE BIG BANG IS AN EXPLOSION

9. FALSE Universe is colder 13 BYA

10. TRUE The Higher the energy the Higher the temperature

11. true Can mass be converted to Energy?

12. The Origin of Light Elements The origin of all the naturally occurring elements fall into two phases: • Big Bang or Primordial Nucleosynthesis —the origin of the “light” elements; and • Stellar Nucleosynthesis — the origin and production of the “heavy elements

13. Nucleosynthesis is the process that creates new atomic nucleus from preexisting nucleons, which is proton neutrons. Primordial or Big Bang Nucleosynthesis refers to the process of producing the “ light elements ” shortly after the Big Bang.

14. HOW DOES BIG BANG NUCLEOSYTHESIS WORK? By means collision and combination of protons and neutrons

15. The energy and temperature of the universe are extremely high to cause the neutrons and protons to combine and form certain species of atomic nuclei in a process called nuclear fusion

16. Through Nuclear Fusion, the light elements- Hydrogen (H) , Helium (He), and small amounts of lithium (Li) and beryllium (Be) were formed. The isotopes produced during the big bang nucleosynthesis were H-1, H-2, H-3, H-4, L-7

17. An Isotope is a form of an element that has the same atomic number of the original element but with different atomic mass or mass number .

18. Helium 4 + Tritium = Lithium Helium 3 + Helium 4 = Beryllium
