These particles have moderate ionizing and penetrating powers and are affected by electric and magnetic fields. What is a beta particle in chemistry? A particle (an electron or a positron) of high velocity and energy emitted during a radioactive decay process is called a beta particle. The ...
Some polonium compounds are prepared for the purpose of research. Health effects Polonium is an extremely dangerous substance. When it breaks down, it gives off alpha particles. These particles are tiny, atom-sized particles that can destroy cells. Polonium is considered to be more than 100 ...
One application for this property includes making a neutron trigger for nuclear weapons [1, 7]. Polonium Poisoning Polonium is highly toxic [1, 5]. Since it emits alpha particles, exposure to this radioactive element increases the chances of cancer [5]. If inhaled, swallowed, or absorbed ...
In 1944, Seaborg, Ghiorso, and James bombarded plutonium-239 with alpha-particles in a cyclotron at Berkeley, California. It was then sent to the Metallurgical Laboratory at the University of Chicago to isolate and analyze the new element. On 11 November 1945, after the end of the World War...
In 1955, Ghiorso and his team at Berkeley, California, conducted an all-night experiment where a sample of einsteinium-253 was bombarded with alpha particles in a cyclotron to produce a new isotope, later detected as mendelevium-256 with a half-life of about 78 minutes. After this, several...
It was only in 1940 when Corson, Segre, and MacKenzie at the University of California synthesized the new element by bombarding alpha particles against bismuth. They were unable to conduct further research as the entire focus had to be given to the Manhattan project during the World War 2 for...
Thechemistryof radium is what would be expected of the heaviest of thealkaline earths, but the intenseradioactivityis its most characteristic property. Itscompoundsdisplay a faint bluish glow in the dark, a result of their radioactivity in which emittedalpha particlesexcite electrons in the other ele...
