Which is the best example of an element?

An element is the simplest form of matter that has a unique set of properties. Examples of well-known elements include oxygen, iron, and gold (see the figure below). Elements cannot be broken down into a simpler substance. Likewise, one element cannot be chemically converted into a different element.

What is an element give 2 examples?

an element is a substance that cannot be split into simpler substances by a chemical means . for example – hydrogen, oxygen, nitrogen, carbon, iron, aluminium, copper, silver and gold some example of elements.

What are differences between an element and a compound?

Main Differences Between Element and Compound Pure substances that are made up of a single variety of atoms are known as elements. A total of 118 different types of elements are there out of which 94 occur in their natural state on earth, whereas, compounds are differentiated by the type of bonds Elements are always represented by numbers and symbols such as sodium or Na.

What are some examples of compounds mixtures and elements?

Example 1

  • Element
  • Compound
  • Mixture
  • Pure Gold (Au)
  • Pure Water (H2O)
  • Sea Water
  • Example 2
  • Helium (He)
  • Table Salt (NaCl)
  • Can a compound also be an element?

    Yes, in chemistry a pure substance means either an element or a compound. Thus, hydrogen, oxygen, sodium, iron, copper etc. are pure substances; and so are compounds such as water, sugar, ammonia, sodium chloride, methane, ethanol etc. A compound is composed of two or more elements combined in a fixed ratio by mass.

    What are 3 examples of compounds?

    Examples of compounds include table salt or sodium chloride ( NaCl , an ionic compound), sucrose (a molecule), nitrogen gas (N 2, a covalent molecule), a sample of copper (intermetallic), and water (H 2O, a covalent molecule).
