Please fill in this chart I need this done as fast as possible please Thank you
Explain your understanding: Use your own words and captured images from the simulation to show you can: Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. Compare and contrast: element, atom, isotope. Given the number of protons, neutrons and electrons, find the mass and name of an isotope. Given the name of an element and the number of neutrons, find the mass of an isotope.
