Study Notes
Conservation of Mass and Electron Configuration
- Table salt, sodium chloride, is created from a reaction between sodium metal and chlorine gas
- The law of conservation of mass states that the mass of the reactants always equals the mass of the products in a chemical reaction
- In a closed system, the mass on the left side of the arrow always equals the mass on the right side of the arrow in a chemical reaction
- Chemical reactions can be described using word equations or chemical equations, with the latter needing to be completely balanced to demonstrate the conservation of mass
- Electron configuration determines the reaction of materials to a magnetic field
- Electrons are placed in atomic orbitals and follow specific laws for distribution and placement
- Hund's rule dictates the filling of orbitals of equal energy
- Pauli's Exclusion Principle states that no two electrons in the same atom can have identical quantum numbers
- Diamagnetic electrons are paired electrons with opposite spins that cancel each other out, resulting in a net spin of 0
- Diamagnetic materials have a slight, negative susceptibility to magnetic fields
- The net spin of an orbital influences the magnetic properties of a material
- The creation of magnetism in materials within a magnetic field depends on the configuration of electrons
