What is electron configuration?
the summary of where the electrons are around a nucleus
What are the quantum numbers?
principal, azimuthal, magnetic, and spin
What were the names of the scientist(s) that discovered the quantum theory?
Niels Bohr and Max Planck
What are the names of the quantum models?
What are the four types of orbitals?
s,p,d and f
What does 1s 2s 2p 3s 3p... stand for?
the electronic orbitals energy levels
What do quantum numbers represent?
Quantum numbers represent the values of a quantum system's conserved quantities
What award did the scientist(s) win for the quantum theory?
Nobel peace prize
Who is the father of quantum model?
Max Planck
What did Schrodinger say about orbitals?
electrons do not follow sharply defined orbits (like in Bohr's model), but rather are found in orbitals
where electrons are located around the nucleus of an atom
Why are quantum numbers important?
they can be used to determine the electron configuration of an atom and the probable location of the atom's electrons
What did Max Planck discover?
discovered the quantum of action, now known as Planck's constant
What is the modern day quantum model?
The modern quantum model extends the idea of energy and the movements of electrons inside the atom
How are the orbitals determined?
determined by the value of the angular momentum quantum number ℓ
How many rules are there for writing electron configuration?
3
What are the roles of quantum numbers?
specify the unique and complete quantum state of any single electron in the atom, and they combine to compose the electron's wavefunction, or orbital.
What is the name of the physicist that is known for the investigations of atomic structure and also for work on radiation?
Niels Bohr
Why were quantum models created?
created when the Bohr model failed to account for the wave properties of electrons
What does the quantum theory say about orbitals
The quantum mechanical model specifies the probability of finding an electron in the three-dimensional space around the nucleus and is based on solutions of the Schrödinger equation
What are the rules for writing electron configuration?
Aufbau Principle, Pauli-exclusion Principle, and Hund's Rule
