Using the periodic table as a model, students are asked to complete a graphic organizer that could be used to predict the charges of stable ions formed from atoms in a group on the periodic table.
Atoms are __________ because they have the same number of protons and electrons. However, based on valence electrons, some atoms will easily gain or lose electrons to other atoms in order to achieve noble gas electronic structure. __________are atoms that have gained or lost electrons. Atoms that have __________ electrons have a positive charge and are called __________. Atoms that have __________ electrons have a negative charge and are called __________.

The diagram above represents the formation of lithium oxide from its elements. Which of the following statements provides the best explanation of the chemical reaction?
Two atoms of lithium and one atom of oxygen share electrons, forming a covalent bond.
Two atoms of lithium each donate one electron to oxygen, forming two positively charged lithium ions and one negatively charged oxygen ion that are attracted to one another, forming an ionic bond.
