Ionization energy is the energy required to remove an electron from a gaseous
atom or ion.
Phosphorus first ionization energy 1011.8 (eV)
P 3- is the most common ion because it has 5 valance elections so its going to
form ions in which 3 electrons are taken to fill the valance shell to 8
Electron negativity is a measure of the tendency of an atom to attract a bonding
pair of electrons.

2.19 is the electron negativity of Phosphorus
Interesting Facts About
Phosphorus
 Hennig Brand discovered phosphorus in 1669, in
Hamburg, Germany, preparing it from urine.
(Urine naturally contains considerable quantities
of dissolved phosphates.)
 White phosphorus is highly toxic. Skin contact
can result in severe burns. Red phosphorus
(provided it is not contaminated with white
phosphorus) is considered non-toxic.
 Phosphorus is a vital plant nutrient
