Unit 16 nuclear chemistry

Nuclear reaction A reaction in which the nucleus of an atom is changed affecting the identity of that element What are some differences between chemical reactions and nuclear reactions? Elements may be changed in a nuclear reaction but are only rearranged in a chemical reaction What is the strong nuclear Read more…

Unit 3-part 2: Nuclear Chemistry

electromagnetic radiation (EMR) high energy particles with no mass given off by different objects photons “packet” of energy that moves through space, all types of EMR fall into one of these “packets” electromagnetic spectrum (EMS) entire range of possible energies given off my EMR Non-ionizing radiation low energy radiation, not Read more…

Nuclear Chemistry

Niel’s Bohr • In 1913 Niels’ Bohr, a Danish physicist proposed a new model for the hydrogen atom •He proposed that the electron has certain orbits that it has to stay in that circle the nucleus •The orbits can also be called ATOMIC ENERGY LEVELS Niels Bohr •An electron can Read more…

Nuclear Chemistry: Unit 5

Most chemical reactions involve The exchange or shafing of electrons which does not affect the nucleus How is nuclear chemistry different than other chemical reactions? Bc it involves changes in the nucleus Transmutation When the nucleus of one element is changed into the nucleus of a different element Which means Read more…

Nuclear Chemistry (Notes)

Discovery of Radiation Henri Becquerel 1896 – wrapped photographic film in black paper, put uranium on top and left it in the sun – the photograph was “exposed” so he figured the uranium had absorbed and emitted sunlight – did same experiment on cloudy day…film was still exposed – concluded Read more…

Nuclear Chemistry Review

Radioactivity Process by which nuclei of unstable isotopes emit radiation Subatomic Particles in the Nucleus In the nucleus of an atom, there are protons (p+) and neutrons (n0) Radioisotope An unstable isotope that is subject to radioactive decay Radioactive Decay The breaking down of an unstable atomic nucleus to produce Read more…

Chem 101 Nuclear Chemistry

Nuclear chemistry • study of radiation and processes producing it • radiation is the emission of energetic particles • involves changing the nuclei of atoms Antoine-Henri Becquerel • uranium crystals on black paper that wraps a photographic plate • upon developing the plate, the photographic plate was exposed • uranic Read more…

Chapter 21- Nuclear Chemistry

Energy : Chemical vs. Nuclear -chemical energy is associated with making and breaking chemical bonds -nuclear energy is enormous in comparison -nuclear energy is due to changes in the nucleus of atoms changing them into different atoms Radioactivity -stable nucleus remains intact, but great majority of nuclei are unstable -> Read more…

Nuclear Chemistry

nuclear reactions they are a result of interactions in the nucleus with protons and neutrons nuclear chemistry deals with (blank) the nuclei of atoms breaking apart atoms are continuously undergoing (blank) decay radioactive decay nucleus spontaneously breaks down into a lighter nucleus particles undergo radioactive decay in order to achieve Read more…
