- Helium is the second element on the periodic table, meaning it contains two protons in its nucleus. Normally, helium contains two electrons that orbit the nucleus, however you can ionize the helium, which is stripping an electron from the atom. With 2 protons in the nucleus of the atom, what will be the centripetal acceleration of the electron in an ionized helium atom? ( the electron or it’s at a radius of 29.3 x 10^-12 m around the nucleus)What is the magnitude of the electrical force between two uranium nuclei placed a distance of 1.42 x 10^-12 m apart from one another? 1.642 N 0.580 N 0.966 N 1.256 NA Which would best describe the force on an electron placed at point A?
