∙ 15y agoPure sodium is classified as a metallic solid. It has a metallic bonding structure where the sodium atoms are arranged in a crystal lattice held together by a sea of delocalized electrons.
Sodium is an alkali metal element. It does not exist in it's elemental form on earth since it oxidizes quickly. It is highly reactive with water and a fiery explosion is often the result if the two come into contact.
Sodium chloride is a compound made up of sodium and chlorine ions. It is commonly known as table salt and is a crystalline solid at room temperature.
Sodium metal is an element. It is a pure substance made up of only one type of atom, which is sodium.
Iron oxide is not a pure substance because it is a chemical compound composed of iron and oxygen atoms in a specific ratio. Pure substances are made up of only one type of atom or molecule.
Yes, there is typically a small amount of sodium in ice cream as it is a common ingredient in the recipe to enhance flavor and balance sweetness. However, the sodium content may vary depending on the brand and type of ice cream.
Sodium sulfide is classified as an ionic solid. It is composed of sodium cations (Na+) and sulfide anions (S2-), which are held together by strong ionic bonds.
Sugar is classified as a crystalline solid.

Sodium Chloride is an ionic solid.
Solid
Silver would be classified as an element, which is a type of pure substance.
Sodium chloride is a compound made up of sodium and chlorine ions. It is commonly known as table salt and is a crystalline solid at room temperature.
NaOH is a white crystalline solid that is deliquescent, which means that it absorbs moisture from the air. It is also a strong base that can hurt you if you touch it or ingest it. Handling Sodium Hydroxide makes your fingers feel slippery because it is turning the fat in you fingertips into soap. Don't handle it.
Calcium (Ca) is classified as an alkaline earth metal. It is a reactive metal that is commonly found in solid form as an element with a silvery-white color.
Gold is a pure substance with its own unique chemical and physical properties. It is classified as a solid state of matter at room temperature and pressure.
Yes, common salt (sodium chloride) is a pure substance because it is composed of only one type of molecule, which is sodium chloride.
Iron is classified as an element because it is a pure substance made up of only one type of atom - iron atoms. In its solid form, iron atoms are closely packed together in a regular, repeating pattern that gives the substance its characteristic properties.
