Ionic bonding Flashcards
1
Q
Ionic bonding takes place between what type of elements?
A
Between metals and non-metals
2
Q
Why do atoms react to form ionic bonds?
A
To achieve and electron configuration of a noble gas.
3
Q
What charge do the metal and non-metal ions make?
A
Electrons transferred from metals to non-metals. Metal: lose electrons( +)
Non-metals: gain electrons( - )
4
Q
What forces of attraction holds a giant ionic lattice?
A
Strongs electrostatic forces of attraction between oppositely charged ions.
5
Q
List (and explain where necessary) 4 properties of ionic compounds
A
- High MP/BP
- Do not conduct electricity unless dissolved or molten (ions can move and carry charge when molten otherwise they are in fixed positions).
- Brittle (if ions of the same charge meet, they will repel and structure will break).
- Soluble in polar solvents, eg. water
