1-An atomic cation with a charge of +2 has the following electron configuration: [He] 2s22p4 What is the chemical symbol for the ion?   How many electrons does the ion have?   How many 2s electrons are in the ion?       2-   Ammonium perchlorate (NH4ClO4) is powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen (N2) gas, chlorine (Cl2) gas, oxygen (O2) gas, and water vapor, releasing a great deal of energy. Calculate the moles of chlorine produced by the reaction of 0.90mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits. _____________ 3-How many protons and neutrons are in an atom of Th-229 ?
