Chapter 9 Flashcards
Orbitals can hold no more than ____ electrons each. When two electrons occupy the same orbital, they must have _________ spins. This is known as the __________ principle
Two
Opposing
Pauli exclusion
Full election order
1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s
When orbitals of _____ energy are available, these are first occupied singly with parallel spins rather than in pairs. This is known as _____ rule.
Identical
Hund’s
The s sub shell holds
Only 1 orbital, therefore two electrons max can fit
The p sub shell can hold
3 orbitals, thus having 6 electrons
The d sub shell can hold
5 orbitals equalling 10 electrons
An orbital holds ______ electrons
Two
The f sub-shell has
7 orbitals, holding 14 electrons max
The inner electron configuration for any element is the electron configuration of the _____ _____ that immediately _________ it on the periodic table. We represent the inner electrons with the _____ ____ __ ________
Noble gas
proceeds
Noble gas in brackets
Orbital
How many boxes (that hold two electrons) are present.
1s would have one
4p would have 3
Electrons divided by two
Shell
The 1, 2, 3, 4 etcetera
Subshell
The s, p, d, f
The sizes of atoms decrease as
You go to the right on the periodic table
Sizes of atoms increase as
You move down on the periodic table
Ionization energy is the
Energy it takes to neutralize an atoms electron charge. Being closer to a noble gas requires less energy
