Write how many there are in: Electrons: Write the electron configuration of the following atoms: 1. Sodium Protons: Neutrons: What is an isotope? 2. Carbon 3. Chlorine 4. Neon 5. Lithium How many electrons are able to go in the 1 st, 2 nd, 3 rd and 4 th shell. The configuration tells us a number of things: 1. The number of electrons in the atom 2. The number on each of the shells. 3. The number of shells tell us the period the atom is found in. 4. The last number tells us the group it is in. Draw an electron shell diagram for sodium. State the number of electrons, neutron and protons found in Na, F, Cl, Mg and H. Add to the 5 elements above the period and the group it is found in. 6 QER
