At the freezing point, the particles in an object have no kinetic energy. true or false?

False, no motion would be happening which means it would be kinetic.

False because particles stop moving or study slow down.

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.
