Purple Unit Flashcards
Spherical shape
S sub level
One orbital
S sub level
Dumbbell shape
P sub level
Three orbitals
P sub level
Four shaped like a double dumbbells, one shape, like a dumbbell with the donut
D sub level
Five orbitals
D sub Level
Seven orbitals
F sublevel
An orbital can hold a maximum of two electrons
Pauli exclusion
These two electrons must have opposite spins
Pauli exclusion
Electrons must occupy lowest energy levels first
Afbau
How orbitals of the same energy sublevel must have one electron before electrons can be doubled up in an orbital
Hund’s Rule
Foxes are lines represent orbitals need a sub level. Up or down arrows represent electrons.
Orbital notation
Takes the letters in the numbers of electrons in the orbitals and strings them together
Electron configuration
Short hand, or abbreviated way to avoid repetition, consist of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons
Noble gas configuration
Quantum number formula
Energy level, sub level, orbital, spin
Isoelectronic
Atoms that have the same electronic configuration
Energy levels broken down into
Sub levels
Each sublevel contains one or more ————- that holds ——- —————-
Orbitals, 2 electrons
Attractive force between the valence electrons of different atoms that bind them together
Chemical bond
When atoms obtain eight valence electrons in its outer most energy level
Octet rule
The number of electrons an atom or ion gains, or loses, compared to its neutral atom
Oxidation number
Atoms gain or lose electrons
Ionic bond
Ability to measure, or attract electrons are in a bond
Electronegativity
Change or difference in electronegativity between atoms in a bond
Bond polarity
Nonmetal or metal
Ionic bond
Non-metal and nonmetal
Covalent bond
