   mixture compound element

   3. The center of the atom that contains the proton and neutron is the

   shell nucleus orbit

   4. Changing the number of neutrons of an atom changes its:

   isotope ion charge

   5. Which two particles would be attracted to each other?

   electrons and neutrons electrons and protons all particles are attracted to each other

   

   6.  The neutron has this sort of charge.

                                         Začátek formuláře

   negative alternates positive and then negative no charge
