50 POINTS COME AND GET 'EM please provide full answers. These will not be copy pasted, these answers will instead be used for me to learn. That is how you will get the points.

Locate the main groups of elements in each column on the periodic table, and identify the number of valence electrons there are in each element in a particular group. Infer why some elements are more reactive than others due to their number of valence electrons.

Interpret and describe an example of a chemical formula. Summarize the two parts a chemical formula must have.

Why do atoms bond? Describe examples of the two ways elements complete their valence shell through bonding.

Both acids and bases produce ions when dissolved in water. Propose a way to describe what hydroxide ions (OH−) and H+ (hydrogen) ions are. What do they have to do with acids and bases and the pH scale?

Using what you know about acids, bases and pH, predict what will happen when an acid, such as vinegar, is mixed with water. How would mixing a base, such as baking soda, with water be different?
