Hi I'm Rutherford and I led a team of scientists to discovering the nucleus and protons. Protons are positively charged atoms that are located inside the nucleus. Also I suggested that electrons were scattered in the empty space around the nucleus.
Hi I'm Chadwick one of Rutherford's students who discovered neutrons. Which are neutrally charged atoms that are inside the nucleus. My model of the atom is still widely accepted today.
Hi I'm Bohr and I discovered that electrons are arranged according to energy levels. The lowest level is closer to the nucleus and higher levels are farther away and have more electrons than the close one's do.
