to identify the light elements in the big bang nucleosynthesis

2. Objective!
can give evidence for and explain the
formation of the light elements in the Big
Bang theory

4. What is a Physical Science?

9. PHYSICAL SCIENCE: MATTER AND
ENERGY
Here is where your presentation begins

10. COSMOLOGY
BIG BANG THEORY/BIG BANG
MODEL
NUCLEOSYNTHESIS

12. 1. Give examples of cosmologies from different religions
and cultures based on their beliefs?
2. Do you think there is proof that any of their stories or
cosmologies are true?
3. Why different cultures have the need to explain where
they came from and how the world was created?
4. What are the possible reasons why some people think
science goes against what they believe in?

13. What is the big
bang theory?
explains the
primordial creation
and expansion of
space at the
beginning of time.

14. Astronomers George
Lemaître and Edwin Hubble
were some of first
proponents of the Big Bang
Theory/Model

17. ● This is the most accepted theory
that the vast universe grew out of
something where all matter and
energy were compressed to infinite
density and heated to trillions of
degrees.
●

18. ● A fraction of second after the explosion,
the universe was filled with quarks that
combined to form protons and neutrons.
Matter began to take form light elements
Hydrogen, Helium, Lithium, and Beryllium was
formed through the process of Big Bang
Nucleosynthesis.

23. 02
Nucleosynthesis occurs
when protons and
neutrons combine.

24. “They only have the
same number of
protons but differ in
the number of
neutrons .”
ISOTOPES

25. So when one
proton
combines with
one neutron,
DEUTERON , an
isotope of
hydrogen was
formed.

26. PROTIUM

DEUTERON
Proton and neutron
TRITON
Proton and two
neutron
HYDROGEN HAS THREE
ISOTOPES

27. HYDROGEN has
one proton (H),
He has 2
protons,
Li has 3 , and
Be has 4 and so
on.

28. When DEUTERON (1 proton, 1
neutron) combines with 1 neutron,
TRITON is formed and this is still
hydrogen since it has only one
proton regardless of the number of
neutrons in it.

31. p+

32. DEUTERON = 1 p+ , 1 n
TRITON= 1 p+ , 2 n
3He = 2 p+ , 1 n
4He = 2 p+ , 2 n
7Li = 3 p+ , 4 n

33. So when one
proton
combines with
one neutron,
DEUTERON , an
isotope of
hydrogen was
formed.

34. BIG BANG NUCLEOSYNTHESIS
The Big bang theory predicts that
the early universe was a very hot
place, so hot that even the
particles of protons and neutrons
are destroyed during collision.
