Explanation:
When the charge is +3 means there is lose of 3 electrons .
In the question it says M^+3 has 10 electrons means when the atom is neutral I.e. no loss of electrons there will have been in total of 13 electrons
and in a neutral atom no. of electrons = no. of protons
so, atomic number will be 13.
neutron + protons = mass no.
14 + 13=27
so mass no. is 27 (Al)
