Alfred has a very detailed model of the solar system where each planet is made out of granite rock. since his little sister really liked the model, he spent two weeks in his dad's workshop building her a styrofoam copy. when he picked up the models to take them back inside the house, which physical property would he immediately notice upon picking them up?

Since his little sister really liked the model, he spent two weeks in his dad's workshop building her a Styrofoam copy. When he picked up the models to take them back inside the house, which physical property would he immediately notice upon picking them up? A. color B. conductivity C. density D. ductility

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.

Where is the graph ?
