Section 7.3- Quantum Numbers and Electron Configuration

drawn as 3D around the region that includes 90% of the dots

the compete arrangement of electron in an atom is the atom’s

the Schrodinger equations allow scientists to describe any electron in an atom using four

the four quantum numbers describe the

the first quantum number is known as the

the principle quantum number describes the

the maximum number of electrons in an electron shell is

in general, as the value of n becomes larger, so do the following

each shell is made up of closely grouped

the second quantum number indicated the shape or type of subshell in which an electron is found and is therefore called the

determines SHAPE of orbital

possible subshell shapes

in atoms with two or more electrons, the energy of each electron also depends on

the number of orbitals is limited to the

the number of possible subshells in a particular shell equals the

the third quantum number needed to describe an electron is the

the magnetic quantum number describes the _______________________ of an individual orbital within a subshell

the city, street, and house number are all necessary to locate where a person lives, just as ___ _________ and ______ are necessary to describe the orbital of an electron

each orbital is occupied by a maximum of ___________ electrons

the spin of an electron is described by the fourth quantum number

since there are two possible directions of spin - counterclockwise and clockwise- there are two value for ms:

two electrons in any given orbital must have opposite spins and thus opposite values for the spin quantum number making such electrons

states that no two electrons in an atom may have the same set of four quantum numbers

rule that states that electrons occupy the lowest-energy orbital available, filling in orbitals of successively higher energies until all the electrons are distributed
