Bonding and structures

3 states?
Solid, Liquid and Gas
1 of 13
Stages of transition?
Solid = melting =liquid = boiling = gas Gas = condensing = Liquid = freezing = Solid
2 of 13
Temperature effecting State?
Less melting melting point = Solid Between melting+boiling = Liquid More boiling point = Gas
3 of 13
Form ion?
Atoms loose or gain electrons to obtain full outer shell
4 of 13
Metal example?
Sodium atom (2,8,1) = Sodium ion (2,8) = Looses electron
5 of 13
Non-metal example?
Oxygen atom (2,6) = Oxide ion (2,8) = Gains 2 electrons
6 of 13
Ionic bonds?
- Ionic - Compound - Metallic / Attraction between oppositely charged ions
7 of 13
Ionic bond example?
LiF / Li = looses 1 electron = + F = gains 1 electron = -
8 of 13
Drop and swap method?
Magnesium Fluoride = Mg 2+ F-1 ----> MgF2 / Aluminium Chloride = Al 3+ Cl -1 ----> AlCl 3
9 of 13
How are ionic bonds held together?
By strong electrostatic forces of attraction oppositely charged ions
10 of 13
Properties of ionic compounds?
-Giant ionic lattice - high melting / boiling points - higher charge = stronger force + more energy
11 of 13
Conducting electricity of substances + compound?
Substance = has charged particles / free to move Ionic compound = melted + dissolved in aqua solution
12 of 13
Covalent bonding?
ONLY non-metals , 2 atoms share pair electrons
