Question

A metal ion m with a net 3+ charge loses 3 electrons its oxidation number will be

Answer 1

Answer:

+6

Explanation:

since the charge on metal ion was +3

and it loses 3electrons more hence it gains +3charge more. hence the total charge on metal ion is +6

Answer 2

Its oxidation number will be +6.

Explanation:

Oxidation number represents the number of electrons lost or gained by the atoms of an element in a compound.

Oxidation numbers are generally written with the sign (+) and (-) first and then the magnitude.

when an atom loses electrons, it acquires a positive charge and thus on losing 3 electrons, it acquires 3+ charge.

When a $M^{3+}$ loses 3 electrons , it acquire +6 charge.
