Look at the table. What word completes label 2? Enter your answer Definition & }(c) (1) pure substance that has one type of atom & is made of one or more elements Can it be broken down? & (3) & Yes Examples & aluminium, iron, copper, gold & mathrm(CH)_(4) mathrm(H)_(2) mathrm(O)_(2) Represented by... & symbols and numbers & (4)

## Step 1First, let's understand the table and the information provided. The table has four labels that need to be filled in with appropriate words. Each label describes a type of substance or a property related to substances in chemistry.## Step 2Let's analyze the given information:- Label 1 is described as a "pure substance that has one type of atom." This is the definition of an element.- Label 3 lists examples such as aluminium, iron, copper, and gold. These are all elements.- Label 4 mentions "symbols and numbers," which likely refers to the chemical formulas of substances.## Step 3Now, let's focus on Label 2. It is described as "is made of one or more elements" and "can be broken down." This description fits the definition of a compound. A compound is a substance made from two or more elements that are chemically bonded together and can be broken down into simpler substances.## Step 4To confirm, let's look at the examples given for Label 2: , , and . These are chemical formulas representing compounds and molecules. (methane) is a compound, while (hydrogen) and (oxygen) are diatomic molecules, which can also be considered as compounds in a broader sense.
