Chapter 1 ap chem text book Flashcards
As an electron moves farther away from the radius does the atom emit or absorb energy?
Absorb
As an electron moves closer to the radius does the atom emit or absorb energy?
emit
How do you find the molecular formula?
You find mass of the compound and divide it by the mass of the empirical formula.
metallic character?
decrease as you move left to right on periodic table
Aufbau principle?
subshells in order of increasing energy
Pauli exclusion principle?
no same spin
Hund’s rule?
Occupy orbitals singly and pair up if no other empty orbital.
Electrons further away from the nucleus require less energy to eject and move faster. True or False
True
What do visible and Ultraviolet range do
cause electron emission
Infrared radiation range is used to study what
chemical bonds
Microwave radiation?
shape of molecules
what do elements look like in their excited state on the electron configuration?
an electron is taken from a full sublevel and added to another sublevel.
Are cations smaller or larger than atoms
smaller
Electrons are repelled by other electrons in an atom, therefore there is less attraction to the nucleus. What is this called?
Sheilding
Atomic radius trend?
Increases going down, decreases left to right
