Principles Of Chemistry - Ionic Bonding Flashcards
1
Q

An atom that has lost or gained electrons
2

Ag +
3

4

Fe 2+ OR Fe3+
5
Q

Pb 2+
6

7
Q
Explain ionic bonding in terms of electrostatic attractions
A
- a giant structure of ions = ionic compound
- held together by strong electrostatic forces of attraction between oppositely charged ions
- the forces act in all directs in the lattice, and this is called ionic bonding
8
Q
Why do compounds with giant ionic lattices have high melting and boiling points?
A
- strong electrostatic forces of attraction between oppositely charged ions
- requires a lot of energy to overcome these forces of attraction
- therefore these compounds have high melting and boiling points
9
Q
In what states do ionic compounds conduct electricity?
A
As a solid, the ions are in fixed positions so can’t conduct electricity. However, when molten or in an aqueous solution, these ions are free to move carrying charge and conducting electricity
