1. the arrangement of electrons in an atom, which is prescribed by three rules - the aufbau principle, the pauli exclusion principle, and hunds rule ( 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2} 3 d^{6} )

a. electromagnetic radiation
b. electron - dot structure
c. electromagnetic spectra
d. electron configuration

Explanation:

• 34: Atomic mass is defined as the weighted average mass of the isotopes of an element.
• 35: The Pauli exclusion principle states that a maximum of two electrons can occupy a single atomic orbital but only if the electrons have opposite spins.
• 36: A quantum is the minimum amount of energy that can be gained or lost by an electron.
• 37: The shapes of the orbitals are characteristic. The "p" orbital has a dumb - bell shape, the "s" orbital is spherical, and the "d" orbital has a more complex shape.
• 38: The major energy levels of an atom are described by the principal quantum number.
• 39: Electromagnetic radiation is a form of energy exhibiting wave - like behavior as it travels through space.
• 40: The energy levels contained within a principal energy level are called energy sublevels.
• 41: The arrangement of electrons in an atom, which is prescribed by three rules - the Aufbau principle, the Pauli exclusion principle, and Hund's rule is called electron configuration.
