Metals are shiny, malleable and good conductors whereas nonmetals are dull, brittle an insulators. Aluminum is ductile, malleable, and a good conductor. What other elements are grouped around or in the same column? They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). What is an appliance that starts with letter n? But, what are metals? Chemically, nonmetals tend to have higher values of ionization energy, electron affinity, and electronegativity, and their oxides are acidic. The reason why, in a few cases, aluminium is referred to as a metalloid, from the article: It has some properties that are unusual for a metal; taken together, these are sometimes used as a basis to classify aluminium as a metalloid. of or being a nonmetallic element that has some of the properties of metal; “arsenic is a metalloid element”, an element, such as silicon or germanium, intermediate in properties between that of a metal and a nonmetal; especially one that exhibits the external characteristics of a metal, but behaves chemically more as a nonmetal, An element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. All metals can be made into thin wires, this feature is technically known as ductility. Metal, Nonmetal, or Metalloid?
