Chemistry Chapter 11 Quiz

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.
