what does an oxidation # show about an ion?
it shows the charge that the atom would have if the component was composed of ion.

Boron has an atomic mass of 10.81 amu, according to the periodic table, there is no element with this atomic mass, Explain.
every Boron element has a different mass, so it is averaged.
what decreases electronegativity?
electron shielding
