Protons, and Neutrons, and Electrons oh my!

Sort the following items into its correct group Complete this activity using what you remember about the structure of atoms. Nucleus Proton Neutron Has 99% of the Atom's mass Has positively charged parts Has neutrally charged parts Cloud Electron Has almost no mass Has negatively charged parts Takes up the most space Fill in the missing parts of the table below. Be sure to use your periodic table Element Symbol Atomic Mass # of N # of P # of E Carbon C 12. 6 6 6 Phosphorus P 31 16 15 15 Sodium Na 23 12 11 11 Match the Orbitals Match the picture of the orbitals to the correct title 1st Orbital level (K) 2nd Orbital level (L) 3rd Orbital level (M) 4th Orbital level (N) Label the Orbitals "_(st Orbital" 1st Orbital 2nd Orbital 3rd Orbital 4th Orbital Draw the element Cl Use the pre-made BohrModel below and add the correct configuration of electrons for the element Cl On your drawing above how many electrons were on the last orbital? 3 8 7 0 We call the negative particles on the last orbital of the atom...
