A combination reaction occurs when one or more reactants react to make a product. The general equation for this reaction is A + B --> AB. We did an experiment on it using a bunsen burner. The products we used were magnesium oxide. The word equation we are doing is Magnesium +  oxygen   →   magnesium oxide. In the process of the reaction, we are holding the magnesium on the fire. As this happens we can see the magnesium turn a different colour and state. In our experiment, we observed that the starting state of the magnesium is solid, shiny, malleable, and has a silver colour to it. The end state of the magnesium is crumbly, textured, not shiny, and it’s white instead of silver. The general rule for it is A+B→AB. Magnesium has an electron configuration of 2,8,2. O has an electron configuration of 2,6. Magnesium will lose two electrons to gain a full outer shell and Oxygen will gain two electrons to gain a full outer shell. An atom loses electrons to get a positive charge. An atom gains electrons to get a negative charge. The positive charge is attracted to the negative charge to form a new ionic compound.

Critical literacy question: Why am I reading this? In science, I went on Miss Abernethy's websites to learn about what a combination reaction is. From reading her article I was able to find out the scientific process that is occurring in the combination reaction.
