With the help of Madame Curie and her husband Pierre, Becquerel was able to isolate two other radioactive substances: polonium and radium.They named the predicted particle atomos, meaning indivisible.Here is a chart showing some half-lives of radioactive substances: Who discovered radioactive isotopes. Like Carbon-12 6protons and 6 neutrons and Carbon-14 6protons and 8neutrons.Beta Decay Beta decay is caused by electrons and antineutrinos being emitted by the nucleus.For this to happen, a neutron within the nucleus must be changed into a proton.Taken together, the work of Becquerel, the Curies, Rutherford and others, made modern medical and scientific research more than a dream.Carbon14 with 6 protons and 8 neutrons, is unstable and decays by releasing a beta particle from its nucleus to become a stable isotope, Nitrogen14.After much grueling work, the Curies were able to extract enough polonium and another radioactive element, radium, to establish the chemical properties of these elements.
Although Becquerel did not pursue his discovery of radioactivity, others did and, in so doing, changed the face of both modern medicine and modern science.A look at the use of isotopes reveals just some of the ways in which the pioneering work of these scientists has been utilized.Becquerel was familiar with the work of Wilhelm Conrad Roentgen on December 22 1895, photographed his wife s hand, revealing the unmistakable image of her skeleton, complete with wedding ring. 152,938 Contributions This circuit is used in most electronic digital computers ever built & was invented in 1918 (patent GB148582).This lady thinks that a pair of rubber gloves make a seductive accessory (left) and (right) a swordsman displays his softer side, and an array of weaponry, in an attempt to woo an impressed other half This Russian gentleman (left) hopes that showing how flexible he is in a children's playground will make a potential partner swoon.Des Dichado Radioactive isotopes are used for radioactive dating.

In fact, Carbon is so stable that it is used in a modern process called carbon dating.
