Flashcards in Chapter 8 Deck (23):
0

Bonds in which valence electrons are shared

Covalent bonds

1

shared pair between 2 atoms

Sigma bond

2

Forms when parallel orbitals overlap and share electrons

Pi bond

3

Stronger, shorter, higher bond energy

Multiple bonds

4

Occurs when a greater amount of energy is required to break the existing bonds

Endothermic reaction

5

Occurs when more energy is released during product bond formation than is required to break bonds

Exothermic reaction

6

Is former when Two or more atoms bond covalently

Molecule

7

Acid that contains both a hydrogen atom and an oxyanion is a

Oxyacid

8

Uses letter symbols and bonds to show relative positions of atoms

Structural formula

9

Polyatomic Lewis structures need?

Brackets and a negative or positive sign

10

What does VSEPR stand for

Valence shell electron pair repulsion

11

Condition that occurs when one know if instruction can be written for a molecule or ion

Resonance

12

Forms when one Atom donates both of the electrons to be shared with an Atom or ion that needs to electrons to form a stable electron arrangement

Coordinate covalent bond

13

Angle is 180 degrees

Linear

14

Equally spaced vertices at 120°

Trigonal planar

15

Occurs when there is an unshared pair of electrons

Bent triatomic

16

If there is an unshared pair it will force it into a pyramidal

Trigonal pyramidal

17

109.5 degrees apart

Tetrahedral

18

Process in which atomic orbitals mix and form new, identical hybrid orbitals

Hybridization

19

Attraction of electrons to an atom within a bond

Electronegativity

20

What number decides whether it is ionic or covalent and how do you determine this

Subtract one elements Electronegativity from another and 1.7 if more than 1.7 ionic, less=covalent

21

Form because not all atoms that share electrons attract them equally

Polar covalent bonds

22

Polars dissolve ____
Nonpolars dissolve ____

Polars
Nonpolars
