Ionic, Covalent and Metallic bonding Flashcards
1
Q
Examples of simple molecular
A
H2O, CO2, O2
2
Q
Does simple molecular bonds have a m.p/b.p
A
No low because of the weak intermolecular forces
3
Q
Describe bonding in simple molecular bonds
A
Strong covalent bonds between atoms but weak intermolecular forces of attraction, low m.p/b.p
4
Q
Example of giant covalent lattice
A
Diamond, graphite, silica (sand)
5
Q
What happens when a G1 element reacts with Oxygen
A
Forms an oxide
e.g. 2Na + O2 –> 2Na2O
6
Q
What happens when a G1 element reacts with Water
A
Forms hydroxide and hydrogen
e.g. 2Na + 2H2O —> 2NaOH + H2
7
Q
What would you observe when G1 reacts with H2O/O2
A
Fizzing, move on surface, gets smaller, floats
8
Q
What happens when Potassium reacts with water/oxygen
A
Lilac flame, fizzing, floats
