Are atoms nice sharers OR mean,
evil, disruptive sharers?
+1. Electronegativity: In a
______________ bond, it’s which atom usually has the shared valence electrons.
2. Electronegativity depends on the ________ and the number of _________ __________.
3. ____________ is the most electronegative element on the table.
Electronegativity
+1. As you move down a periodic
table atoms become __________.
2. As you move across the periodic table atoms become _________.
Electronegativity
+
3. As you move across the periodic table atoms become _________ electronegative.
4. As you move down a periodic table atoms become __________ electronegative.
Electronegativity
+5. Polarity measures how
_________________ the charges are in an atom.
Polarity
+ MAD Skillz: Determine which bond is the most polar
1) Determine the electronegativity of each atom. 2) Subtract the bigger number from the smaller
number to get overall polarity.3) The bond with the largest overall polarity is the
most polar
Determine which bond is the most polar.
N-O, C-O, or B-O
+ MAD Skillz: Determine which bond is the most polar
1) Determine the electronegativity of each atom. 2) Subtract the bigger number from the smaller
number to get overall polarity.3) The bond with the largest overall polarity is the
most polar
Determine which bond is the most polar.
H-F, H-Cl, or H-Br
+6. A polarity arrow pictorially
represents the change in charge.
7. The plus end is ________________the arrow end is ________________
Polarity arrows
+ MAD Skillz: Determine which bond is the most polar
1) Determine which atom is more electronegative; it is the negative end
2) The more positive atom receives the positive end.3) The more electronegative atom receives the
negative end
Draw the polarity arrows for the following chemical bonds
H - Cl S - P
