Note that the number of valence electrons for elements in the s and p-blocks of the periodic table is equal to their group number. E.g., Ca is in Group IIA, and has 2 valence electrons. Which it is happy to lose, so it has a +2 charge when these electrons are lost. Sound familiar? We can also write electron configurations for ions, noting that when we do, the ions of representative elements (s- and p-block elements) are isoelectronic (same electron configuration) with the noble gas element with the atomic number closest to their own atomic number. Khan Academy Electron Configuration of lons (4 min) Practice with the below elements. Note that metals lose electrons to become cations that are isoelectronic with the noble gas previous to them, and nonmetals gain electrons to "catch up" with the noble gas that follows them. This is because noble gases have filled valence shells of electrons, which makes them very stable. (This is why noble gases are nonreactive).

4. Dr. Dahm has 15.0 grams of Fe that he places into 150 mL of 8 M HNO₂ (aq). The reaction is done in a sealed bottle that has a volume of 1.50 L, at a temperature of 40°C. Fe (s) + HNO3(aq) Fe(NO3)3 (aq) + H₂ (g) What is the pressure when all of the Fe is used up? If the flask can hold 2.0 atm before the cork blows off how many grams of Fe are still remaining?
