Question

sodium chlorine sodium chloride (diagram is not drawn to scale) which statement is supported by this diagram? sodium chloride is composed of one type of atom. sodium chloride is a mixture. sodium chloride is an element. sodium chloride is a compound.

Explanation:

• Sodium chloride is composed of one type of atom: The diagram shows sodium (one type of atom) and chlorine (another type of atom) combining. Sodium chloride has two types of atoms (\(Na\) and \(Cl\)), so this is incorrect.
• Sodium chloride is a mixture: A mixture has substances that retain their individual properties. In sodium chloride (\(NaCl\)), sodium and chlorine react chemically. It's not a simple physical - mixture. So this is wrong.
• Sodium chloride is an element: An element is made of only one type of atom. Since \(NaCl\) has two types (\(Na\) and \(Cl\)), this is incorrect.
• Sodium chloride is a compound: A compound is formed when two or more different elements chemically combine. Sodium (\(Na\)) and chlorine (\(Cl\)) chemically combine to form \(NaCl\), which fits the definition of a compound.

Answer:

Sodium chloride is a compound.
