QuestionAnswer
electromagnetic spectrum Includes all forms of electromagnetic radiation, with the only differences in the types of radiation being their frequencies and wavelengths
Planck's constant h, which has a value of 6.626x10-34 J*s, where J is the joule.
Photoelectric effect a phenomenon in which photoelectrons are emitted from a metal's surface when light of a certain frequency chines on the surface
atomic emission spectrum a set of frequencies of electromagnetic waves given off by atoms of an element; consists of a series of fine lines of individual colors.
aufbau principle states that each electron occupies the lowest energy orbital available.
hund's rule states that single electrons with the same spin must occupy each equal-energy orbital before additional electrons with opposite spins that can occupy the same orbitals.
electron configuration the arrangement of electrons in an atom, which is prescribed bu three rules: the aufbau principle, the Pauli exclusion principle, and Hund's rule.
Pauli exclusion principle states that a maximum of two electrons may occupy a single atomic orbital, but only if the electrons have opposite spins.
continuous spectrum shines with a connected series of colors, each with unique wavelengths and frequencies.
heisenberg uncertainty principle states that if a fundamentally impossible to know precisely both the velocity and position of a particle at the same time
