Chem Quiz: Electron Configuration

What is the electromagnetic spectrum?

The combination of all the energy on earth.

What is electromagnetic radiation?

The form of energy

If the wavelength is greater, is the energy lower or greater?

lower

If the energy is higher, what is the wavelength?

lower

What thing on the spectrum has the lowest energy?

Radiowaves

What thing on the spectrum has the highest energy?

gamma rays

What thing on the spectrum has the highest wavelength?

radiowaves

What thing on the spectrum has the lowest wavelength?

gamma rays

Which atom did Bohr base his model around?

hydrogen

What did Bohr link an atoms electrons to?

photo emission

What did Bohr say?

electrons can only exist in small paths called orbitals, and electrons cannot exist between orbitals.

In what way was Bohr's model wrong?

He said electrons moved in strategic pathways, which is wrong. His model also really only works for hydrogen because it has one electron.

How do electrons move?

They absorb energy and moves up energy levels (become excited). Then, they fall abck down to ground state.

What do electrons need to move?

An energy source

What are Wave Functions

Gives the probale location of an electron.

Where do electrons exist?

In regions called orbitals

What are orbitals?

3D regions around the nucleus that give a probable location of an electron.

What was Erwin Schrödingers Quantum Mechanical Model of the Atom?

He said four quantum numbers are required to decide the state of the hydrogen atom.

What are the four quantum numbers?

principle (n), orbital (l), magnetic (ml), spin(ms) or (s)

What does the principal quantum number (n) indicate?

main energy levels= 1,2,3,4,...

Do main energy levels have sublevels?

yes

What are the max number of electrons for n

2n squared

What does orbital quantum number (l) indicate?

the shape of orbital sublevels

What numbers of l equal correspond with each sublevel?

l=0=s, l=1=p, l=2=d, l=3=f

What does the magnetic quantum number (ml) indicate?

the orentation of the orbital in space

What are the values of the ml?

integers from -l to + l

What are the possible values of the 4 quantum numbers?

n=1,2,3,4,... ms= + 1/2 or -1/2 ml = -l to +l l= 0 to (n-1)

What does n show?

the energy level, if n =5 we write 5l. so basically n=x we write xl. (l gets filled in based on the sublevel value it indicates.)

How many electrons can a single electron hold?

2

What is the max number of electrons that can occupy an s orbital?

2

What is the max number of electrons that can occupy the entire subshell of p orbitals?

6

What is the max number of electrons that can occupy the entire subshell of d orbitals?

10

What is the max number of electrons that can occupy the entire subshell of f orbitals?

14

What number of orbitals does each sublevel have?

s=0, p=3, d=5, f=7

Whats the electron cloud?

Positions where there is probability of finding electrons. The higher in density, the more probability.

Explain the Quantum Mechanical Model?

Electrons are located in specific energy levels with no exact path around the nucleus. The model estimates the probability of finding an electron in a certain spot.

What is the Aufbau Principle?

Electrons fill bottom up, they fill the lowest energy levels first.

What is the Pauli Exclusion Principle?

There is a max of 2 electrons per orbital with different spins.

What is Hunds Rule?

Lowest enegry/most stable configuration occurs when not double filled. (Electrons fill individually first)

What is K?

orbital notation, ground state

What are valence electrons?

outermost electrons in the highest energy level.

Louis dot diagrams

The dot diagrams, try to put them far away from eachother

How is the anomaly Cr configured?

[Ar] 3d to the fifth power 4s to the first power

How is the anomaly Mo configured?

[Kr]4d to the fifth power 5s to the first power

How does the f block behave?

The f block also does not behave how we would expect.
