Polarity
Caused by unequal sharing of electrons between atoms.
what is polarity
this element has an electronegativity of 1.00
what is calcium
The space occupied by valence electrons in a molecule, either a bonded pair(s) or a lone pair.
what are electron domains
How are the atoms represented in Ball-and-Stick Models?
by the balls
Minty
When two atoms with different electronegativity values share electrons, there will be a partial negative charge on one atom and a partial positive charge on the other atom, and therefore
Polarity in the molecule
electronegative elements placement
what is the upper right side of the periodic table
how many electron domains does H2O have
4
the shape of H2O (ball and stick model)
the smell of long and stringy models
sweet/putrid
NaCl polarity
2.23
Non-electronegative elements placement
what is the lower left side of the periodic table
CCl4
->electron domains
->lone pairs
-> 16
->12
this is the more accurate of the two models
space filling
T or F
shape of a molecule is a better indicator of smell than the functional group
true
above 2.0 polarity these compounds are found
what are ionic compounds
These elements give electrons
what are non electronegative elements
F2
->bonded pairs
-> lone pairs
->1
->6
haow are the bonds represented by the ball and stick models
by the sticks
How can something with an Alcohol functional group smell sweet?
the shape would have to be stringy
LiF=>
->polarity
->polar or non polar
->ionic or covalent
->3.00
->polar
->ionic
these elements take electrons
what are electronegative elements
O2
->total electron domains
->bonded electron domains
->lone pair domains
->5
->1
->4
the shape of Formaldehyde (CH2O)
what is trigonal planar?
(dont cheat 👁️👁️)
Chapter 7 slides: molecule R(C10H20O)
->shape
-> functional group
->smell
->frying pan
->alcohol (pro tip the ending of the name tells u the functional group check slide 2)
->minty
