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!

Marissa is adding numbers in her head. Which part of her brain is she using? 1.cerebrum 2.cerebellum 3.brain stem
inn [45]
Cerebrum is the part of the brain that we use for imagination, thinking, judgement etc. It is also the largest part of the brain 

Cerebellum is in charge of stuff like the spinal cord 

and the brain stem is the part of the brain that helps us move. (if you watch the walking dead in one of the episodes it teaches this xD) 

hope this helped (:
