   The Chemistry oh Phosphorous

   Its structure consists of 4 atoms covalently bonded in a tetrahedral arrangement4. This arrangement means the molecules are weakly bonded, so are easy to break therefore it has high reactivity. Other properties include its boiling point of 280�c and melting point of 44�c, its distinct garlic odour, and its high toxicity.

   Fertiliers organ Vs inorganic

   Farmers often have problems with over fertilization when using fertilizers. With organic materials, the probability of this is far less as the concentrations of nutrients in organic materials are relatively low in comparison to inorganic fertilizers. Organic fertilizers provide a slow release of nutrients to plants, as micro-organisms need to

   Organic and Inorganic Fertilisers

   (Gardening techniques by Jonathan Edwards.) Inorganic fertilisers are immediately available to plants because they are soluble in water. This can be a big disadvantage though because the fertilisers can easily be leached from the soil by heavy rains. Nitrates from inorganic fertilisers are very soluble and easily leached; if it

   Successive Ionisation Enthalpies Ionisation enthalpies increase after successive electrons are removed, due to the higher number of protons, giving a stronger attraction, therefore requiring more energy to remove. Also there are sharp jumps as you move onto the next shell.
