Intramolecular Forces
What type of bond is formed when the electrons are transferred between a metal and a nonmetal?
Ionic
In a Lewis Dot Diagram, we look at the electrons in the outermost shell of an atom. What is the special name for these types of electrons?
Valence electrons
If a molecule has 2 electron domains, and 0 lone pairs on the central atom, what shape will the molecule be?
Linear
HBr is a polar molecule. In a bond between H and Br, which atom would have the partial negative charge?
Br
What are the letters of the 4 atomic orbitals (blocks found on the periodic table)?
S, P, D, F
What type of covalent bond is formed when the electrons around the atoms in a molecule are NOT equally shared?
Polar covalent bond
If you were to draw a Lewis Dot Diagram of Carbon, how many dots (valence electrons) would you draw around it?
4

10 electrons
What type of covalent bond is formed when the electronegativity difference between the atoms in a molecule ranges from 0 to 0.4?
Non-polar covalent bond
In a Lewis Dot Diagram of a molecule, to show a triple bond between atoms, we draw 3 lines. How many total electrons are shared in this triple bond?
6
How many lone pairs are on the oxygen atom in a water molecule?

1s22s22p4
What value must the electronegativity difference between two atoms be greater than or equal to, to be considered a polar bond?
0.5
When drawing a Lewis Dot Diagram, we typically make sure that each atom is happy with a full octet. Which element on the periodic table is an exception and is happy with LESS than an octet?
Boron (would also accept H or He)
How many electron domains are on the central atom of NH3?

What type of intermolecular forces would be present in two NH3 molecules if they bonded together? (There are 3)
LDF, dipole-dipole, H-bonding
2p2 <-- What do each three of these characters represent?
Big 2 = energy level, p = atomic orbital/sublevel, Little 2 = # of electrons in that level

ONLY BUZZ WHEN YOU ARE FULLY COMPLETE! If two H2O molecules bonded together, and two SO2 molecules bonded together, which bonded pair would have a higher melting/boiling point? ***Response should have correct VSPER structures, dipole moments/partial charges drawn, and polarity identified for answer to be correct.
