Answer:

118

Explanation:

The periodic table is an arrangement of elements in rows and columns. The vertical columns are called groups while the horizontal rows are called periods.

The eighteenth group in the periodic table are called noble gases. All the elements in this group are gases. Coincidentally, the heaviest element, oganesson belongs to this group and has atomic number 118.

This element exits as a gas and it is the heaviest known gas.

Describe the development of the atomic bomb. Why were even the scientists who worked on the program skeptical about its effectiv
Norma-Jean [14]
It varies from country but I’ll focus on the US because they actually developed it first. It was a long and tedious process. This was all completely new and everything was theoretical. There were several small scale tests that were done at first that proved that it would be possible. The first bomb that would later be dropped on Hiroshima was made from uranium. The process of refining the uranium to make the bomb took a very long time especially because the ordinary factory workers that refined it didn’t actually know what they were doing. The second bomb that was made out of plutonium and would be dropped on Nagasaki was much quicker to produce but much harder to find plutonium to use. The majority of the scientists that spearheaded the bomb in Las Almos New Mexico didn’t even know exactly what they were making. They all worked on separate projects and then a few of the top scientists like Robert Oppenheimer would focus on assembling the various projects into an actual working bomb. In summary it was an incredibly secret project and took a very long time because it was something that had never been done before. The scientists who worked on it were skeptical because at first they thought of it just as an experiment and a scientific breakthrough. Then when the first test happened and it was revealed what this bomb could really do the scientists truly realized what they had created. It did so much damage and because of that they started to become skeptical of their creation. It would kill (and did) millions. As Oppenheimer would later put it after the bombing of Hiroshima to president Truman, “I have the blood of millions on my hands.”

Anyway I hope this helped. If this is for a school and you just need an answer that’s fine but if you are interested about this in general I recommend “Bomb” by Steve Shienken. It’s a good book and very factual and interesting.
