1. in the models, what particles do the colored and plain sesame seeds represent? what particles do the poppy seeds represent

Ok the answers to the hole .doc is 
1. Neutrons, Protons, and Electrons
2. Nucleus
3. Neutrons and Protons
4. Electrons
5. Because they represent different things (I would put this in your own words)

Answer 1) : The colored and plain sesame seeds represent the subatomic particles neutrons and protons. Explanation :

The attached model of the atom has subatomic particles as neutrons and protons; which are present in the center of the nucleus of the atom. Where neutrons are neutrally charged particles in the nucleus and protons are positively charged particles present in the nucleus of the atom.

Answer 2) The poppy seeds represent the electrons.Explanation :

The poppy seeds used in this atomic model represents the revolving electrons around the the nucleus of the atom in orbits. These are negatively charges subatomic particles which revolves around the nucleus.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
