Chemistry Exam 2 Flashcards
What is the trend for electro negativity in the periodic table?
As you go up and from left to right, the electro negativity increases.
What is the trend for Ionization Energy in the periodic table?
As you go from left to right and from bottom to top, the ionization energy increases.
What is the trend for atomic radius in the periodic table?
As you go from RIGHT TO LEFT AND FROM TOP TO BOTTOM, the atomic radius increases.
How does losing and gaining an electron affect the radius of an atom?
If you LOSE AN ELECTRON, you become smaller.
If you GAIN AN ELECTRON, you become larger.
What are the possible orbitals?
S,p,d,f,g,h,i,j
What is Hund’s Rule?
Other boxes must be filled before putting electrons in the same box.
What does paramagnetic mean?
Unpaired electrons
What does Diamagnetic mean?
All e- paired.
What is the Pauli Exclusion Principle?
All electrons must have unique quantum values.
