Study Notes
Atomic Mass and Atomic number
- The atomic mass of an element is primarily determined by the combined mass of its protons and neutrons.
- The number of protons in an atom is equal to its atomic number.
Electronic Structure
- The energy associated with an electron increases as its distance from the nucleus increases.
Suborbital Quantum Number (l)
- The suborbital quantum number (l) describes the shape and size of the region where an electron is most likely to be found.
- The shape and size of the region vary depending on the energy level of the electron.
Electronic Structure of Ions
- The electronic structure of an ion may sometimes not reveal the level from which an electron was lost, especially in transition elements.
- This occurs because relative orbital energies can change when electrons are added to orbitals.
Groups in the Periodic Table
- There are eight groups in the periodic table, corresponding to the filling of s and p orbitals.
- The principal quantum number of these orbitals is equal to the period or row number of the table.
- In periods 2 and 3, the s and p orbitals are filled in a standard fashion.
Chemical Bonding
- The entity providing a pair of electrons in a chemical bond is called the donor species.
- The acceptor species is electron-deficient and has an empty orbital capable of overlapping with the orbital from the donor.
- An example of this type of bond is the boron-trifluoride etherate complex.
