Study Notes
Key Vocabulary in Chemistry
- Attract: Describes the phenomenon where unlike charges pull towards each other.
- Repel: Refers to the interaction between like charges that push away from each other.
- Neutral: Indicates the charge of a neutron, which is neither positive nor negative.
- Shell: Represents the designated location of an electron within an atom.
- Nonmetals: Elements characterized by high ionization energies, implying they hold onto their electrons tightly.
- Periodicity: Describes the repeating patterns observed within atomic structures across the periodic table.
- Noble Gases: The group of elements recognized for their minimal reactivity, classified as the least reactive family of elements.
Electron Configuration
- Maximum of 10 electrons can occupy a single d subshell, crucial for understanding electron distribution in atoms.
Radioactive Decay
- True or False: The nuclear product of radioactive decay is termed the daughter nuclide.
- Emission of a Beta particle has specific effects, including no change in overall mass and the addition of a proton of insignificant mass to the nucleus.
Characteristics of Radiation
- True or False: Gamma ray emissions occur without observable changes in mass or nuclear charge.
- True or False: The half-lives of unstable isotopes can range dramatically from milliseconds to billions of years.
- True or False: Nuclear fusion represents the process of atoms combining to form a heavier element.
Energy in Fusion Reactions
- Energy in fusion reactions is produced from a small amount of gas that is converted to energy, highlighting the power potential in nuclear processes.
