Want this question answered?
-3 electrons are gained,i.e,3 electrons are lost by Al and 3 electrons are gained by the other atom nearby.
two electrons lost
Xe neither gain or lose electrons= 0
Only one electron lost.
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
it has gain 4 electrons
Usually three will be lost.

two electrons lost
There is zero NET loss or gain of electrons
Xe neither gain or lose electrons= 0
Only one electron lost.
Only three electrons.
the oxidation number
There are many factors when it comes to Boron. If it were to form an Ion, then it would drop a total of three electrons.
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
Oxygen is in group 6, and so it has 6 valence electrons. It needs to more to make an octet, so it will GAIN TWO electrons, and become negative 2, i.e. O^2-.
