    Which is not a type of elements

    ?
    A Metalloids Correct Answer Incorrect Answer
    B Metals Correct Answer Incorrect Answer
    C Gases Correct Answer Incorrect Answer
    D Non - metals Correct Answer Incorrect Answer

    Solution

    Gas is not a type of element since all except gases are the forms of elements.  A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile. In chemistry, a nonmetal is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity.
