Term
3. What is a line spectrum/atomic emission spectrum? How is this diffferent from the continuous spectrum?
Definition
Line spectrum/atomic emission spectrum only shows certain colors or wavelengths. Continuous shows all colors and wavelengths.
Term
Why is an atomic emission spectrum often called an atoms fingerprint?
Definition
Each element has their own characteristic line spectra
Term
Why is the Bohr model only accurate for hydrogen?
Definition
Bohr couldn't predict other's wavelengths using math b/c they had more than 1 electron.
Term
What is Heisenburg's uncertainty principle? How does this help show that Bohr's model isn't entirely correct?
Definition
 -Both position and momentum of an electron cannot be simultaneously known. This helps show that the Bohr model isn't entirely correct b/c it assumes we do know the momentum and position of an electron, but we don't so we have to use probability to estimate the electrons location.
Term
What is an orbital?
Definition
Space around the nucleus where there is a high probability of finding an electron
Term
List the types of orbitals in order of increasing energy
Definition
s p d f
Term
How many different types of s orbitals exist?
Definition
1
Term
What does an S orbital look like?
Definition
º
Term
What is the electron capacity of the s sublevel? Of one s orbital?
Definition
2 and 2
Term
How many different types of P orbitals exist?
Definition
3
Term
What do p orbitals look like?
Definition
Term
What is the electron capacity of the p sublevel? Of one p orbital?
Definition
6 and 2
Term
How many different types of d orbitals exist?
Definition
5
Term
What is the electron capacity of a d sublevel? Of one d orbital?
Definition
10 and 2
Term
Pauli exclusion principle
Definition
an atomic orbital may describe at most 2 electrons
Term
Aufbau principle
Definition
electrons fill lower energy orbitals first
Term
Hund's rule
Definition
electrons occupy orbitals of the same energy in a way that makes the number of electrons with the same spin direction as large as possible
