each energy level has how many sublevels?
it has one or more sublevels which they describe the specific atomic orbitals.
principle quantum number?
represents the energy level represented by the letter N.
N = 1 ... first energy level. N= 2... second energy level.
each energy level represents a period on the periodic table.
what are the four different sublevels?
S , P , D , F . These are called blocks
how many orbitals and electrons does S have?
One, and two electrons .
how many orbitals and electrons does P have?
three, and six electrons.
how many orbitals and electrons does D have?
five, and ten electrons.
how many orbitals and electrons does F have?
seven, and fourteen electrons.
each sublevel has what?
they have a certain number of orbitals, and can only hold so many electrons.
the specific way in which the atomic orbitals are filled,
the address of an element on the periodic table.
rules for electron configuration?
Aufbau principle- electrons fill the lowest energy level first
-the lower the quantum number the lower the energy
-orbitals (s)= lowest energy... P,D,F= most energy
Pauli exclusion principle?
one atomic orbital can only hold 2 electrons.
shorthand noble gas?
go up one column and go all the way to the right.
arrows in an orbital rotation represent?
electrons have a?
negative charge, when paired they want to repel one another
electrons have opposite spins which allows them to?
share the same orbital without repelling each other.
how do we show the opposite spins of an electron?
by drawing one going up and the other one going down.
whose rule do we follow when creating orbital notations for every element?
every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied and all electrons in singly occupied orbitals have the same spin.
electrons will be alone in an orbital before they?
