This is because two or more atoms is known as a molecule and for electron sharing to occur then there must be a minimum of two atoms which is also known as a molecule present in the sharing process.
The net ionic equation of borax hydrolysis would be:
<span>Na2B4O7 + 7H2O-----------------> 2 NaOH + 4 H3BO3
</span>
Wherein 2 moles of sodium hydroxide and 4 moles of boric acid are produced by the hydrolysis.

Ca3(PO3)2
Oxidation numbers:
Ca ---- +2
P----x
O---- -2
+2*3 +x*2 - 2*6 = 0
6 + 2x -12 = 0
2x = 6
x = +3
Oxidation number of P is +3.
