C3 - Structure and Bonding Flashcards
1
Q
Solids
A
- Strong forces, particles compact
- Fixed Positions
2
Q
Liquids
A
- Weaker forces
- Can move past each other, indefinite shape
3
Q
Gases
A
- Very weak forces
- Particles spread out, moving in random directions
4
Q
State Symbols
A
- Solid (s)
- Liquids (l)
- Gases (g)
- Aqueous, dissolved in water (aq)
5
Q
Ions
A
-Charged particles, electrons transferred
6
Q
Metal Ions
A
-G1/2 elements loose electrons (positive ions, +1 charge)
7
Q
Non Metal Ions
A
-G6/7 elements gain electrons (negative ions, -1 charge)
8
Q
Ionic Bonding
A
-Transfer of Electrons between Metal and Non Metal
9
Q
Metallic Bonding
A
-Transfer of Electrons between Metal and Metal
10
Q
Covalent Bonding
A
-Transfer of Electrons between Non Metal and Non Metal
11
Q
Ionic Compound Properties
A
- Strong Bonds (high melting/boiling points)
- Cant conduct electricity when solid, can when liquid (electrons move freely)
- Giant Ionic Lattice Structure
12
Q
Polymer
A
- Long chains of repeating units
- Atoms in Polymers joined by a Covalent Bond
13
Q
Giant Covalent Structures
A
- Atoms bonded by strong forces, high melting/boiling points
- No charged particles, don’t conduct electricity
- Examples: Diamond, Graphite, Silicon Dioxide
14
Q
Diamond
A
- Carbon Atoms bonded to 4 other Carbon Atoms
- No free electrons/ions
15
Q
Graphite
A
- Carbon Atoms bonded to 3 other Carbon Atoms
- Arranged in sheets
- Electrons delocalised, conducting electricity
