    27Al13 + ? yields 30P15 + 1n0

    Subscripts must add out.
    Superscripts must add out.

    I am changing it to show the atomic number first and mass second.
    13Al27 + ?? ==>15P30 + 0n1
    13 + ? = 15 + 0 so ? must be 2
    27 + ? = 30 + 1 so ? must be 4
    What do you know that has an atomic number of 2 and an atomic mass of 4. That must be He or written as I have done it, make it 2He4.
    That's how it's done.
