Question
Answer
the 3D path an electron probably takes within an energy level   orbital  
🗑
evidence for energy levels comes from the _____ of the elements   line emission spectra  
🗑
proposed that electrons behave as particles and waves (dual wave-particle theory)   De Broglie  
🗑
the bending of a wave as it passes by the edge of an object   diffraction  
🗑
the overlapping of waves   interference  
🗑
His UNCERTAINTY PRINCIPLE states that it is impossible to determine the position and velocity of an electron or any other small particle at the same time   Heisenburg  
🗑
developed the WAVE EQUATION, which laid the foundation for Quantum Theory   Schrodinger  
🗑
describe the energy state and location of electrons   quantum numbers  
🗑
electrons that are not in the highest occupied energy level are called___   inner shell electrons  
🗑
the first quantum number is called ____ and indicates ____   principal quantum number; main energy level occupied by the atom  
🗑
specify the properties of atomic orbitals and the properties of electrons within the atomic orbitals   quantum number  
🗑
the second quantum number is called ___ and indicates ___   angular momentum quantum number; the electron's sublevel and the shape of the orbital the electron is moving in whith its sublevel  
🗑
s orbital has a ___ shape   sphere  
🗑
p orbital has a ___ shape   peanut  
🗑
third quantum number is called ___ and tells ___   magnetic quantum number; a specific orbital section an electron is in at a given point in time along the x, y, z axis  
🗑
fourth quantum number is called ___ and indicates ___   spin quantum number; direction of electron's spin  
🗑
the arrangement of electrons in an atom   electron configuration  
🗑
3 types of electron configuration:   1.) electron configuration notation 2.) orbital notation 3.) noble gas notation  
🗑
an electron occupies the lowest orbital that can receive it (electrons enter the orbitals closest to the nucleus first)   Aufbau Principle  
🗑
no 2 electrons in the same atom can have the same set of 4 quantum numbers (at most, an atomic orbital may contain 2 electrons with opposite spin)   Pauli's Exclusion Principle  
🗑
the idea that electrons witht he same spin eneter each orbital section before electrons with opposite spin eneter is known as ___   Hund's Rule  
🗑
pair of electrons with opposite spin in the same orbital   electron pair  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
