Solution

Solution Steps

Step 1: Understanding the Breakdown of Starch

Starch is a carbohydrate that is broken down into glucose through a process called hydrolysis. This involves the enzymatic action of amylase, which cleaves the glycosidic bonds in starch.

Step 2: Determining the Likely Bond Formation

An atom with 2 electrons in its outermost shell is likely to form an ionic bond. This is because it can easily lose these electrons to achieve a stable electron configuration, typically forming a cation.

Step 3: Identifying the Role of a Chemical Absorbing $\mathrm{H}^+$ Ions

A chemical that absorbs $\mathrm{H}^+$ ions acts as a base. Bases are substances that can accept hydrogen ions, thereby reducing the concentration of $\mathrm{H}^+$ in a solution.

Final Answer

Starch is broken down into glucose by the process of $\boxed{\text{hydrolysis}}$.
An atom with 2 electrons in its outermost shell will most likely form a/an $\boxed{\text{ionic bond}}$.
A chemical which absorbs $\mathrm{H}^+$ ions will $\boxed{\text{act as a base}}$.
