Answer 22

IMF break into molecules

Question 23

Network Covalent

Answer 23

Stronger then single covalent
charcoal graphie diamonds SiO2 SiC Abestos
Insol
Many covalent bonds rpeating long chains or layers stronfest of all bonds

Question 24

highest vapor pressure

Answer 24

covalent

Question 25

ionic finding bondstrength

Answer 25

1. magnitude of charges (add up e-) 2. larger size if same magnitude

Question 26

metallic finding bondstrength

Answer 26

1. sea of electron sizd ( bigger amount of e- lost) 2. size greater effective nuclear charge smaller

Question 27

Molecualr comp bondstrenghth

Answer 27

1. compare imf 2. size- larger= strong bond

Question 28

Ionic compound

Answer 28

M&NM transfer of e- posititve charge- cation metal negative charge - anion nonmetal

Question 29

Ionic property

Answer 29

crystalline solids at rt high mp and bp conduct electricity when molten or aqueous greatest ionic character

Question 30

Molecular property

Answer 30

NM+NM share e- do not conduct electricity solid liquid gasses low mp and bp

Question 31

polar

Answer 31

nonmetals of unequal strength do not share e- equally one slightly neg with more electronegativity one slightly pos

Question 32

Nonpolar

Answer 32

two nonmetal atoms are the same time and share the bonding electrons equally because they have the same electronegativity

Question 33

Polar Molecule

Answer 33

A molecule whos structure has oppositely charged sides witha dipole. High in ionic character due to prtially charged poles on the molecules

Question 34

Nonpolar molecule

Answer 34

Either the molecular strucutre has no oppositely charged poles or the poles cancel eachother out little ionic character

Question 35

Strongest bond

Answer 35

covalent bonds molecules do not break apart into smaller particles ithout being involved in chemcial reactions

Question 36

Metallic solid

Answer 36

cations held together in a sea of valance electrobs the larger the sea of electrons the stronger the bond is if 2 metals have the sme charge, then depends on the atomic radii. Smaller metals with fewer occupied levels have greater effective nuclear charge and strong bonds

Question 37

single bond

Answer 37

weakest longest sigma

Question 38

double bond

Answer 38

stronger shorter sigma pi

Question 39

triple bond

Answer 39

strongest shortest sigma pi pi
