identify each element as a metal, metalloid, or nonmetal. 1. silicon (si) nonmetal 2. gold (au) metal 3. sulfur (s) nonmetal 4. barium (ba) metal 5. carbon (c) nonmetal 6. sodium (na) metal

Answer

Brief Explanations:

Silicon is a metalloid with properties intermediate between metals and non - metals. Gold is a metal known for its high conductivity and malleability. Sulfur is a nonmetal, brittle and a poor conductor of heat and electricity. Barium is a metal, reactive and metallic in appearance. Carbon is a nonmetal, exists in various allotropes like diamond and graphite. Sodium is a metal, highly reactive and soft.

Answer:

  1. Metalloid (Silicon)
  2. Metal (Gold)
  3. Nonmetal (Sulfur)
  4. Metal (Barium)
  5. Nonmetal (Carbon)
  6. Metal (Sodium)
