  • Atom is to molecule as letter is to what?
    Atom is to molecule as letter is to word; atoms combine to form molecules just as letters combine to form words.
  • What is the difference between an element and a compound?
    An element is a pure substance made of only one kind of atom, while a compound is a pure substance made of two or more different elements chemically bonded together.
  • How does an element differ from a compound?
    An element consists of only one type of atom and cannot be broken down into simpler substances, whereas a compound is made of two or more different elements chemically bonded and can be separated into those elements by chemical means.
  • Which of the following describes a compound?
    A compound is a substance composed of two or more different elements that are chemically bonded together.
  • What element is always present in an organic compound?
    Carbon is always present in an organic compound.

    Water is the most abundant chemical compound in the human body.
  • What is the difference between an atom and an element?
    An atom is the basic unit of matter, while an element is a pure substance made up of only one kind of atom.
  • How is a compound different from an element?
    A compound contains two or more different elements chemically bonded together, while an element contains only one kind of atom.
  • A pure substance made of only one kind of atom is called what?
    A pure substance made of only one kind of atom is called an element.
  • A compound differs from an element in that a compound:
    A compound consists of two or more different elements chemically bonded together, while an element contains only one type of atom.
  • Which element is present in all organic compounds?
