Radioactive - The atoms decay over time and emit radiation. Isotope - The same number of protons, but a different number of Neutrons. Ionized - The number of electronic do not equal the number of protons. Atom - The basic unit of a chemical element. Atomic number - the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table. Electron - a stable subatomic particle with a charge of nega...

• Chapter 1 o Unit conversions- use dimensional analysis ▪ Milli, centi, kilo o Particle diagrams ▪ Solid- is a material with a defined shape in which the atoms or molecules are packed together closely. ▪ Liquid- is a material that flows and takes on the shape of its container because its particles can flow past one another. ▪ Gas- is a material that has no fixed shape or volume because its particles are widely spaced and move rapidly past one another o Mass/moles/molecules o...

AP Chemistry | Unit 3 Progress Check: MCQ: 2023. (two diagrams shown above) Which particle diagram shown above best represents the strongest intermolecular force between two ethanol, C2H6O, molecules? C) Diagram 2, because it shows the formation of a hydrogen bond between an H atom bonded to an O atom with an O atom from another molecule. (Li+, Mg2+, Na+, and Ca2+ cations shown above) The diagram above represents four cations, all shown to the same scale. Which cation would be predicted by ...
