bond character and bonding Flashcards
(8 cards)
1
Q
what are ionic bond characteristics?
five
A
- high MP/BP
- crystal structures
- usually soluble in water
- conduct electricity when dissolved in water
- insoluble when melted
2
Q
based on electronegativity, how is a bond ionic?
A
1.7 or more difference between the EN
3
Q
what is an ionic bond?
A
when two ions have a complete transfer of VE
4
Q
what is a nonpolar covalent bond?
A
bonding electrons shared equally between two atoms
5
Q
what is a polar covalent bond?
A
bonding electrons shared unequally between two atoms with partial charges on atoms
6
Q
based on electronegativity, how is a bond polar covalent?
A
0.5 or more difference between the EN
7
Q
based on electronegativity, how is a bond non-polar covalent?
A
small to no difference in EN, they form no dipole
8
Q
how is an ionic bond stronger or weaker based on lattice energy?
A
- higher charge/smaller size is stronger
- lower charge/bigger size is weaker
