Key Idea 1
David's parents weren't your normal parents. David's dad stayed away at work while his mom sat at home. David would go around the house and gather household items and mix them together. His first mix of substances did not really work. The stuff began to bubble so he …show more content…
The elements David found are distinguished by the number of protons in their nuclei. Hydrogen has one proton. Therefore hydrogen’s atomic number is 1. The combined number of protons and neutrons in a nucleus is the atomic weight or mass. Elements are generally occurred in different forms which are distinguished by the number of neutrons in their nuclei. There are three isotopes of hydrogen: H-1, H-2, and H-3. The first one has one proton and no neutrons. The second one has one proton and one neutron. The third one has one proton and two neutrons. David learned that all radioactive elements and isotopes have a half-life; which means that the amount of time required for the intensity of their radiation decay by half.

While David harbored nuclear ambitions, his experimenting to this point was still largely unfocused. He soon began to work with materials that are inherently dangerous and could cause terrible harm by passive exposure alone. One of the highlights of David’s year came when he departed for an annual eight-week stay at Lost Lake Summer Camp. David thrived at Lost Lake and ultimately became a senior patrol leader, which gave him a real sense of responsibility and authority. David got expelled from camp for blowing a hole in the roof when they accidentally ignited the stockpile of powered magnesium he had brought to make fireworks. He was allowed back another year until, he …show more content…
His love began when he was little and he would conduct little experiments using household items. As he grew older, he received more information and his experiments got bigger and more dangerous. One experiment took a turn for the worse and injured many people. David was then taken to jail for his experiment and effects due to it. The book related to a couple things we have learned this first semester. It told about how David used the periodic table and how the combined number of protons and neutrons in a nucleus make up the atomic mass. It also talked about measuring and equaling chemicals which Mr. Sanders has also taught us this
