Answer:
Electron
Explanation:
The answer would be the electron because it is constantly moving so its location cannot be accurately determined
Density = mass/volume = 800/200 =4 g/cm^3
Solid- particles are packed tightly together so they don’t move much
Liquid- particles are still close together but move freely
Gas- particles are neither close together nor fixed in place
Electron affinity corresponds to the energy released when an electron is added to<span> a </span>neutral atom in the gas phase<span>.
