Iodine follows Tellurium in the periodic table of the elements due to its higher atomic number. The atomic number (the number of protons in the nucleus) of Iodine is 53, while that of Tellurium is 52. The elements are not arranged by atomic mass.
<u>Answer:</u> The original element is ![_{84}^{212}\textrm{Po}](https://tex.z-dn.net/?f=_%7B84%7D%5E%7B212%7D%5Ctextrm%7BPo%7D)
<u>Explanation:</u>
Alpha decay is defined as the process in which alpha particle is emitted. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units.
The released alpha particle is also known as helium nucleus.
![_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_2^4\alpha](https://tex.z-dn.net/?f=_Z%5EA%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ-2%7D%5E%7BA-4%7D%5Ctextrm%7BY%7D%2B_2%5E4%5Calpha)
For the given alpha decay process of an isotope:
![^{Z}_{A}\textrm{X}\rightarrow ^{208}_{82}\textrm{Pb}+_2^4\alpha](https://tex.z-dn.net/?f=%5E%7BZ%7D_%7BA%7D%5Ctextrm%7BX%7D%5Crightarrow%20%5E%7B208%7D_%7B82%7D%5Ctextrm%7BPb%7D%2B_2%5E4%5Calpha)
<u>To calculate A:</u>
Total mass on reactant side = total mass on product side
A = 208 + 4
A = 212
<u>To calculate Z:</u>
Total atomic number on reactant side = total atomic number on product side
Z = 82 + 2
Z = 84
The isotopic symbol of unknown element is ![_{84}^{212}\textrm{Po}](https://tex.z-dn.net/?f=_%7B84%7D%5E%7B212%7D%5Ctextrm%7BPo%7D)
Hence, the original element is ![_{84}^{212}\textrm{Po}](https://tex.z-dn.net/?f=_%7B84%7D%5E%7B212%7D%5Ctextrm%7BPo%7D)
<u>No, the captain should continue using the current technology.</u>

<h3>How Nuclear Fusion Reactors Work?</h3>
When hydrogen atoms fuse, the nuclei must come together. However, the protons in each nucleus will tend to repel each other because they have the same charge (positive). If you've ever tried to place two magnets together and felt them push apart from each other, you've experienced this principle firsthand.
To achieve fusion, you need to create special conditions to overcome this tendency. Here are the conditions that make fusion possible:
High temperature gives the hydrogen atoms enough energy to overcome the electrical repulsion between the protons.
- Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun's core).
- At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about.
- The sun achieves these temperatures by its large mass and the force of gravity compressing this mass in the core. We must use energy from microwaves, lasers and ion particles to achieve these temperatures.
High pressure squeezes the hydrogen atoms together. They must be within 1x10-15 meters of each other to fuse.
- The sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core.
- We must squeeze hydrogen atoms together by using intense magnetic fields, powerful lasers or ion beams.
