IONIC BONDING Flashcards
1
Q
Definition of ionic bonding
A
The strong electrostatic attraction between positive and negative ions
2
Q
What is an ion
A
a charged atom (due to losing or gaining an electron)
3
Q
If an atom loses an electron, what is its charge?
A
+
4
Q
if an atom gains an electron, what is its charge?
A
-
5
Q
What is the structure of ionic bonds?
A
Ionic lattice
6
Q
Low or High boiling points?
A
HIGH
7
Q
Explain the boiling point of ionic compounds. (3 points)
A
- they have a giant ionic lattice
- which has strong ionic bonding
- which requires lots of energy to overcome
8
Q
larger ionic charges produce ……………. ionic bonds and therefore require ………. energy to break the ionic bonds
A
LARGER
MORE
9

In what states are ionic compounds able to conduct electricity?
A
dissolved in water (aq), molten (l)
11
Q
Explain the conductivity of ionic compounds…
A
mobile electrons (which can carry charge)
