2. I. Identification:
• 1. A reaction where smaller nuclei collide together
to make larger nuclei
• 2. What do you call the theory wherein it states
that the universe came from singularity
• 3. Elements heavier than iron are formed in what
type of nucleosynthesis?
3. • 4. A reaction where there is splitting of a nucleus to form two or
more smaller, more stable nuclei
• 5. What type of radioactive decay where the mass number of
the remaining nucleus decreases by 4 and the atomic number
decreases by 2?
• 6. What type of radioactive decay where the mass number and
atomic number of the nucleus remain unchanged, and no new
element is formed?
4. • 7. He is known as the father of periodic table
• 8. He rearranged the elements in the periodic table on
the basis of atomic number
• 9. He discovered the nucleus in the atom
• 10. What is the other name of synthetic elements?
5. II. True or False
• 11. The periodic table is compose of 7 group and 18
periods
• 12. There are 116 elements in the periodic table
• 13. In beta decay the atomic number of the remaining
nucleus increases by 1 but the mass number does not
change.
• 14. Helium is the first element in the periodic table
6. • 15. It is in the stellar nucleosynthesis where cobalt to
uranium was formed or the atomic number 27-92
• 16. In getting the sub-atomic particles of atom, the
Proton, Electon and Atomic Number are the same
• 17. Synthetic elements are elements that does not occur
naturally on Earth
7. • 18. The universe is 4.5 billion years old
• 19. Technetium was the first man-made element
• 20. James Chadwick discover neutron that is found in
atom, which is negatively charge particle
8. III. Enumeration:
• 1-2. What are the two elements formed in the big
bang nucleosynthesis
• 3-5. What are the three types of nucleosynthesis
• 6-8. What are the three types of radioactive decay
9. • 9-10. What are the two elements that are sometimes
classified as synthetic elements but can also have small
trace amounts naturally
• 11-13. What are the three sub-atomic particles of atoms
• 14-15. There are two number word found in the periodic
table. What do you call this number word found in each
elements.
