Card preview (23)

#1
Front (Question)

Covalent Bond

Back (Answer)

Bond where atoms share electrons

#2
Front (Question)

Bond lengths - = ≡

Back (Answer)

triple(≡) = shortest single(-) = longest

#3
Front (Question)

Bond energy (lowest to highest)

Back (Answer)

single(-) = lowest triple(≡) = highest

#4
Front (Question)

Electronegativity trend

Back (Answer)

increases up and to the right

#5
Front (Question)

Ionic bond

Back (Answer)

atoms lose and gain electrons and are bonded by pos/neg attraction

#6
Front (Question)

Polar bond

Back (Answer)

Electrons are not shared equally (one atom pulls the electron more than the other because it is more electronegative)

#7
Front (Question)

Atoms greater than or equal to what atomic number can break the octet rule

Back (Answer)

15

#8
Front (Question)

Formal charge

Back (Answer)

of electrons around the atom in a lewis structure (- bond = 1) compared to the # of valence electrons that atom brings

#9
Front (Question)

Resonance structures

Back (Answer)

A lewis structure that represents the possibility of different locations where bonds can exist

#10
Front (Question)

Sum of individual formal charges =

Back (Answer)

Total charge of the molecule

#11
Front (Question)

VSEPR

Back (Answer)

Valence Shell Electron Pair Repulsion (Electrons want to get as far away from each other as possible)

#12
Front (Question)

Geometry (in lewis structures)

Back (Answer)

Structure represented by bonds and lone pairs

#13
Front (Question)

Shape (lewis structure)

Back (Answer)

Structure represented by only the bonds

#14
Front (Question)

2 Bonds (find geometry, bond angle, and hybridization)

Back (Answer)

Geometry = Linear Bond angle = 180 Hybridization = sp

#15
Front (Question)

3 bonds (find geometry, bond angle, and hybridization)

Back (Answer)

Geometry = trigonal planar Bond angle = 120 Hybridization = sp2

#16
Front (Question)

4 bonds (find geometry, bond angle, and hybridization)

Back (Answer)

Geometry = tetrahedral Bond angle = 109.5 Hybridization = sp3

#17
Front (Question)

5 bonds (find geometry, bond angle, and hybridization)

Back (Answer)

Geometry = trigonal bipyramid Bond angle = 90 120 Hybridization = sp3d

#18
Front (Question)

6 bonds (find geometry, bond angle, and hybridization)

Back (Answer)

Geometry = octahedron Bond angle = 90 Hybridization = sp3d2

#19
Front (Question)

Lone pairs, double bonds, and triple bonds do what to bond angles

Back (Answer)

They all repel more than single bonds which will make the bond angles smaller depending on how you look at it

#20
Front (Question)

Axial plane

Back (Answer)

Up and down/side-to-side linear AXIS

#21
Front (Question)

Equitorial plane

Back (Answer)

Flat plane, similar to an equator

#22
Front (Question)

Pi bond

Back (Answer)

Double or triple bond where orbitals overlap side to side

#23
Front (Question)

Sigma bond

Back (Answer)

Single bond where orbitals overlap head to head
