Chapter 2: Electrons and the Periodic Table Flashcards
What predicts atom/ion behavior?
the location of the electrons
What model first showed what causes an atom to emit only a certain wavelength of light?
Bohr Model
What atom is the only atom that works with the Bohr Model of the Atom
hydrogen
What is “ground level” for a Bohr atom?
n=1
What is the term for an electron going from a lower energy level to a higher one?
absorption (excitation)
What is the term for an electron going from a higher energy level to a lower one?
emission (relaxation)
What are absorption and emission both known as?
electronic transfers
With a Bohr atom, which energy level jump is the biggest?
n=1 to n=2
As the “n” number increases, what happens to the amount of energy?
energy increases
Electrons behave as:
waves
Light behaves as a:
particle
What equation is the Quantum Mechanical Model based on?
Schrodinger’s Equation
What do quantum numbers tell us?
location, orientation, shape, and spin of an electron
What does the principle quantum number (n) tell us?
the size and distance from the nucleus
What does the angular momentum quantum number (L) tell us?
the shape
What “L” number goes with each shape (S,P,D,F)?
S=0
P=1
D=2
F=3
What does the magnetic quantum number (ML) tell us?
the orientation of the orbital in space
What does the spin quantum number (MS) tell us?
the spin of the electron (either 1/2 or -1/2)
T/F: every electron has a unique set of quantum numbers?
TRUE!
What is known as the likelihood of finding an electron within any volume?
orbital
