For each of the following, write the electron configuration for each element on the reactants side. Then write the electron configuration for the ions that would be formed when making the ionic compound product. (You may use noble gas core configurations) Example: Sodium and chlorine Na+Cl→Na1++Cl1- →NaCl 1s22s22p63s1 + 1s22s22p63s23p5 → 1s22s22p6 + 1s22s22p63s23p6 → NaCl Calcium and fluorine Potassium and sulfur Magnesium and oxygen Zinc and nitrogen Lithium and bromine 6.

Predicting lonic Compound Formulas Activity Ionic compounds are compounds composed of two substances which have a preferred ionic charge. The number of each type of compound must be balanced so that the ionic charge of the combination is zero, and the positive and negative charges balance. For each of the compounds below, you must interpret the name of the ionic compound using the naming rules to decide what elements or polyatomic groups make up the compound. Using the information on...

1. A convenient source of acetylene, C2H2, is a compound incorrectly called "calcium carbide," which suggests a formula of Ca2C, composed of two Ca2+ ions and a C4- ion. Calcium carbide actually has the formula CaC2, and reacts with water to form calcium hydroxide and acetylene gas, which burns easily. Its actual formula suggests that it might contain two C- ions, rather than one C4 Using a Lewis structure for acetylene, the correct formula for calcium carbide, and molecular orbital...
