WebbIce is not correct since the particles are stuck to one position and vibrate. In the air, the intermolecular distance is very high. Steam is similar to air and the particle distance in this state is also large. WebbAtoms contain protons and electrons in equal numbers so therefore have no net charge to them. Where these particles differ is their mass which is measured in atomic mass units; a proton has 1 mass unit with 1 positive electric charge, a neutron has 1 mass unit with neutral charge, and an electron has a very small (almost immeasurable) mass with 1 …
