Orbital Notation Flashcards
What does orbital notation show?
shows all electrons in energy level order (Aufbau); all Orbitals shown with electron pairing (Hund); showing opp. spin for pairs in each orbital (Pauli)
What does the Lewis Dot Notation show?
only the valence electrons
What does the Bohr Model Diagram show?
all electrons per energy level
ex. does not delineate between sublevels
Electron Configuration
use of superscripts to show the # of electrons per sublevel
Noble Gas Configuration
use the Nobel Gas and show configuration of electrons after that Nobel Gas
Isoelectronic def.
atoms of two diff. elements with same # of electrons
Describe photoelectric effect
when light shines on a metal and it has enough energy –> electromagnetic radiation, electrons are emitted
Def. of Quantum
the minimum amount of energy that can be lost/ gained by an atom
What is the formula of energy and frequency?
E=hv
What is Planck’s constant?
6.626 x 10 34 JxS
Each particle of light carries a _________ of energy.
quantum
Photon:
a particle of EMR that has 0 mass and carries a quantum of energy
How is the energy of electromagnetic radiation related to frequency?
DIRECTLY related. (frequency increases and energy too)
What must happen in order for an electron to move from a ground state to an excited state?
electrons must absorb enough energy that will cause it to move to a higher energy level
How hydrogen can produce four different colors when it only has one electron?
Electrons from multiple energy levels emit energy so diff wavelengths/energies can happen. (diff colors represent a move from diff energy levels)
