1:46 Name: Period: Atomic Structure Activity For each problem, a nucleus is provided. Draw the correct number of protons, neutrons, electron shells, and (valence) electrons. 1. The Beryllium (Be) atom has 4 protons, 4 electrons (2 valence e), and 5 neutrons. It is on the 2nd period, so it has two electron shells. 2. The Helium (He) atom has 2 protons, 2 electrons (2 valence e'), and 2 neutrons. It is on the Ist period, so it has one electron shell. Name: Period: 3. The Sodium (Na) atom has 11 protons and 12 neutrons. It is on the 3rd period, so it has three electron shells. It has I valence e.
