The picture above shows the reaction that occurs when heated magnesium (Mg) metal is placed in a test tube containing chlorine gas (Cl2). The atomic structure of these elements allows scientists to predict how elements react and the outcomes of these reactions. The periodic table, shown helps scientists make these predictions.
A few classmates share their explanations for the outcome of this reaction in Figure B. Finally, a classmate creates the following model outlining the reaction between Mg and O2

Hydrogen (H) can act as a metal or a nonmetal. It forms either a +1 or -1 charge depending on which element it is reacting with.
Use your knowledge of ionic bonding to determine which charge H would use when it bonds with a metal such as Mg

A student measured the mass of magnesium ribbon before lighting it on fire. The student took the mass after the magnesium fully reacted and formed magnesium oxide.
Mass of magnesium: 1.3gMass of magnesium oxide: 2.1g
Use the law of conservation of mass to determine the mass of oxygen that reacted with magnesium?
