3.3 - Ionic Bonding Flashcards
1
Q
ions
A
atoms that have lost or gained electron(s)
2
Q
cation
A
positive ion
3
Q
metal atoms lose electrons to
A
become positively charged ions
4
Q
nonmetal atoms gain electrons to
A
become negatively charged ions
5
Q
anion
A
negative ion
6
Q
group five ion charges
A
-3
7
Q
group six ion charges
A
-2
8
Q
group seven ion charges
A
-1
9
Q
compounds have
A
no overall charge
- ions cancel out
10
Q
ionic bonding in terms of electrostatic attractions
A
held together by strong electrostatic forces of attraction between oppositely charged ions
11
Q
why compounds with giant ionic lattices have high MP/BP
A
- strong electrostatic forces of attraction between oppositely charged ions
- requires lots of energy to overcome
12
Q
ionic compounds only conduct electricity when molten/aqueous solution
A
solid - ions fixed
molten/aqueous - ions free to move, carrying charge
