Question
This group of elements has properties that are opposite those of metals. ______________________
- Luster
- Non-metals
- Metalloids
- Metals
Hint:
A solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.
The correct answer is: Non-metals
- Non-metal elements have properties that are opposite to those of metals.
- A non-metal is a chemical element with several properties that are opposite those of a metal.
- Non-metals are natural materials that do not generate heat or electricity and are structurally fragile (that is, they cannot be easily rolled, shaped, extruded, or pressed). Hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium are non-metallic elements on the periodic table.
