Atomic Number is the same as the number of protons in an element. Mass Number is the number of Protons + Neutrons in an element. Atomic Number: 6 means 6 Protons Mass Number: 15 means 15 atoms that are a proton/neutron. We are given out of the 15 atoms, 6 of them are protons, so the other 9 must be Neutrons. 15 - 6 = 9 so there must be 9 Neutrons.There are 9 Neutrons in atom's nucleus.Give Brainiest if you think this is the best answer and explanation. Thanks!

¹⁵₆X - 6 protons - 6 electrons - 15-6 = 9 neutrons :)
