Question

1.What are the three constituent particles that make up an atom?Where is each found?

2.Which force brings stability to the nucleus? Which brings instability?How do these two relate to each other? Note: explain this question conceptually, no calculations are required

3.Distinguish between atomic number, neutron number, and mass number. Which one of these could also be called the “nucleon number”?

4.The uranium isotope,92235U, is the part of a fuel rod in a nuclear power plant that produces energy.Find the number of protons, neutrons, and electrons in this isotope, assuming it is electrically neutral.

Explanation / Answer

1) Neutron, proton and electron. Neutron amd proton are found inside the nucleus and electron revolves around the nucleus in stable orbits.

2) Nuclear force brings stability to the nucleus and the instability is caused by the electrical force between the protons and the radiactive decay of the nuclear particles. As the protons are close enough the force between them is one of the reason for the instability.

3) Atomic number is the number of protons in the neutral atom.
   Neutron number is the number of neutron in the atom and Mass number is the sum of number of protons and neutrons present inside the nucleus.

4) Protons=92=Electron
   Neutrons=235-92=143.
