Study Notes
Ion Formation
- Neon is least likely to form an ion due to its stable electron configuration.
- Fluorine, magnesium, and sodium readily form ions.
Electron Loss
- Iron (Fe) is most likely to lose an electron, thus forming a cation among the options provided.
Ion Naming
- An ion ending in -ate is typically a polyatomic anion, indicating a larger group of atoms than monatomic ions.
Diatomic Molecules
- Properties of diatomic molecules include that the type of bond may vary; it can be nonpolar covalent, polar covalent, or ionic, depending on the specific elements involved.
Chemical Naming
- Nitrous Oxide is properly named Dinitrogen oxide, indicated by its chemical formula N2O.
- Nitrogen Dioxide is referred to as Nitrogen dioxide, corresponding to its formula NO2.
- A compound with the formula N2O3 is called Dinitrogen trioxide.
Systematic Names
- CS2 is systematically named Carbon disulfide.
- XeF4 is appropriately named Xenon tetrafluoride.
Properties of Water
- Water reacts violently with sodium, demonstrating a distinct chemical property that differs from physical properties like melting point.
Physical Properties of Gold
- All listed properties of gold, such as characteristic color, density, and electrical conductivity, are considered physical properties.
Quantum Number
- The principal quantum number reveals the energy level of an electron in an atom.
Orbital Shapes
- The shape of the 3p orbital is described as a dumbbell.
Energy Sublevels
- The second principle energy level contains two energy sublevels.
F Orbitals
- Each energy level in an atom can contain up to seven f orbitals, which are present beyond the principal quantum number two.
