Hi there!
Welcome To OpenStudy :-) 
Any ideas as to what the answer maybe?

kinged · Answer

This is the classic case where there's nothing to explain, just something to answer.

morgengarner · Answer

no not really i mean i thought neutrons but idk

pooja195 · Answer

Neutrons is correct. 
"Different isotopes of the same element have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons. Isotopes have different mass numbers, though, because they have different numbers of neutrons." ~wiki

thank you

"Isotopes have different mass numbers, though, because they have different numbers of neutrons" <--this bit. 
Yw. :)

unklerhaukus · Answer

the nuclei number is the sum of the protons and neutrons, so this will also differ between isotopes

pooja195 · Answer

I'm assuming there can be 2 answers for this one :/

kinged · Answer

An atom just has one nucleus in any case, no, they don't differ in it.

kinged · Answer

And, no, there shouldn't be two answers for it.

unklerhaukus · Answer

consider isotopes of the element hydrogen :

                                      protons,  neutrons,  nuclei 
hydrogen-1                          1             0            1
hydrogen-2 (deuterium)       1             1            2
hydrogen-3 (tritium)            1              2           3
