Question

1. Ca atomic number 2. H2O fission 3. nuclear decay element 4. nuclear synthesis fusion 5. η compound 6. positive charge electron 7. e neutron 8. number of protons in nucleus proton

Answer 1

Um, since I'm unsure what your question is, I think you're referring to the Periodic Table, which in that case, it's #6. ;-)

Answer 2

Answer: Explanation:

1. Ca → element

Ca is a symbol of calcium element categorize as alkali earth metal.

2. → compound

Compound is a substance made up of two more than two different elements.

3. Nuclear decay → fission

Fission is defined as process in which heavier unstable nucleus divide itself into two or more smaller stable nuclei with release of large amount of energy.

4. Nuclear synthesis → fusion

Fusion is defined as process in which two or more nuclei combines together to form an larger nucleus with release of large amount energy.

5. η → neutron

One of the subatomic particle of an atom located in the nucleus of an atom with no electrical charge.

6. Positive charge → proton

One of the subatomic particle of an atom located in the nucleus of an atom with positive electrical charge.

7. e → electron

One of the subatomic particle of an atom located inside an atom and outside the nucleus of an atom with negative electrical charge.

8. Number of protons in nucleus → atomic number

Atomic number of an atom is equal to the total number of protons present in the nucleus if the an atom.
