Ionic Bonding Flashcards
1
Q
Ion
A
An atom with a positive or negative charge
2
Q
Metals in ionic bonding
A
Lose electrons and become positively charged ions (cations)
3
Q
Non-metals in ionic bonding
A
Gain electrons and become negatively charged ions (anions)
4
Q
Ionic compounds
A
A compound containing ions of two different elements
5
Q
Electrostatic forces
A
Forces of attraction between oppositely charged ions
6
Q
Ionic compounds: bonding
A
Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions
7
Q
Ionic compounds: melting and boiling points
A
- High melting and boiling points (because of strong electrostatic forces of attraction between ions that require lots of heat energy to overcome)
8
Q
Conductivity of ionic compounds
A
- Cannot conduct electricity when solid (ions are fixed)
- Can conduct electricity when molten or in aqueous solutions (ions can move and carry charge)
