Exam 5 Flashcards
What type of state is an atom with excess energy in?
Excited
What is the lowest possible energy level called?
Ground State
How do electrons jump between energy levels?
Absorb or emit energy in the form of a photon
What is an orbital?
An area with no sharp boundaries that allows the probability of an electron to be determined.
What level does the d sublevel start at?
Energy level 3
What property helps to determine how electrons are arranged?
Opposite spin
What is the Pauli exclusion principle?
An atomic orbital can hold a maximum of 2 electrons, and those electrons must have opposite spins
What are core electrons?
The inner electrons that are not involved in bonding atoms
What are valence electrons?
The outer electrons
What is ionization energy?
The energy required to remove an electron from a gaseous atom
What is the equilibrium equation?
K=[products]/[reactants]
What does it mean when K>1?
The reaction favors the products and is spontaneous
What is a solution?
A homogenous mixture made up of the solvent and the solutes
What is a solvent?
The substance present in the largest amount
What is a solute?
