Study Notes

Chemistry Chapter 11 Summary

The Richter scale measures the magnitude of earthquakes, and it ranges from 1 to 10.
Wilhelm Rontgen is credited with the discovery of X-rays in the 19th century.
When an atom of uranium undergoes fission, it creates Barium-142 and Krypton-91.
Otto Hahn was awarded the Nobel Prize in Chemistry in 1944, but Lise Meitner and Fritz Strassmann also worked on the discovery of fission.
Nuclear equations need to be balanced, and some involve chemical reactions while others involve nuclear reactions.
Chemical processes do not always involve the rearrangement of protons.
The number 36 represents the number of protons in an element.
A representation of an alpha particle is missing in the text.
Nuclear equations that involve beta decay appear unbalanced because a neutron is converted into a proton and an electron during beta decay.
Isotopes have different numbers of protons, electrons, and neutrons, and their symbols indicate these numbers.
An isotope of (_97^243)Bk contains 97 electrons.
The symbols for isotopes (_58^83)Xe and (_93^144)Np are missing in the text.
The symbol for the isotope with 62 protons and 88 neutrons is missing in the text.
The symbol for the isotope with atomic number 68 and mass number 167 is (_68^167)Er.
Marie Curie contributed to our modern-day understanding of the atom.
Elements at the very bottom of the periodic table are most likely to be radioactive.
