an ion M3+ contains 10 electrons and 14 neutrons.What are the atomic mass and mass number of the element M ? name the element

The atomic number of element is "13" and the atomic mass is "13+14=27u", the name of the element is "aluminum".

the atomic no. of the element m is 10( bcoz no. of electron = no. of proton = atomic mass )

the mass no.  of the element m is 24 (bcoz mass no.= no. of proton + no. of neutron)
