Simplest whole number ratio.
10g H 80g O
Amount of H atoms = mass/ Ar
10/1 = 10 mol
Amount of O atoms = 80/16 = 5 mol
so ratio 10: 5 2:1
H2O
Ions
Anotações:
They give each other the electron
When ionic compounds form + ions attract - ions and arrange into ionic lattice
The electrostatic force of attraction between oppositely charged ions called ionic bond
Very strong and need a lot of energy to break and overcome forces. Very high boiling point.
2+ ions have a higher melting point than + as they attract more strongly.
