What is the smallest unbreakable unit of a compound?
molecule
What are the similarities and differences of the two compounds?
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule.
What is the major difference between a compound and a mixture?
Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances.
What are two differences between a compound and a mixture?
Mixtures are the impure substances, made up of two or more physically mixed substances and not in the fixed ratio. Compounds are the pure form, made up of two or more chemically mixed elements and in a fixed ratio. Mixtures can be homogenous or heterogeneous in nature, but compounds are generally homogenous.
How do you tell if a substance is a compound?
If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture.
Is oxygen a compound or element?
Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.
What is compound and its properties?
A compound is a unique substance that forms when two or more elements combine chemically. A compound always has the same elements in the same proportions. The properties of compounds may be very different from the properties of the elements that form them. Some compounds form rigid frameworks called crystals.
Is silver element or compound?
Silver is a chemical element with the symbol Ag (from the Latin argentum, derived from the Proto-Indo-European h₂erǵ: “shiny” or “white”) and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.
Does silver react with anything?
Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. The tarnish that develops over time on silverware and other silver-plated objects is silver sulfide. Silver does not react readily with water, acids, or many other compounds.
