Part G calcium and sulfur Enter the lons formed by these elements and separate your answers with a comma (e.g., Sr+, AD3-). cation, anion = Ca2+, S2- Submit Previous Answers Correct Use the groups on the periodic table to determine the charge that an atom will form by losing or gaining vale electrons to obtain a stable electron configuration. Part 1 Enter the formula for the ionic compound formed by the ions in Part G. Express your answer as a...
The octet rule states that atoms in molecules share electrons in such a way that each atom has a full valence shell. Determine whether each structure has the correct number of electrons and obeys the octet rule. Classify structures that have the correct number of electrons and obey the octet rule as valid, and those that do not as invalid.

Chemical equations of reduction–oxidation (redox) reactions can be quite nontrivial to balance. To do so, you begin with balancing the number of electrons some particles lose in oxidation and other particles gain in reduction. Consider a reaction between potassium permanganateKMnO4 andhydrochloricacidHCl(aq), which can be used in a lab to produce chlorine gas Cl2. In this reaction, a MnO− 4 ion is reduced to a Mn2+ ion by getting electrons from Cl− and losing its oxygen atoms to bind with H+...
