Guida verificata passo dopo passo1
Understand the properties required for a metal to be used in shiny trim and plating on cars: it must be corrosion resistant and have a reflective appearance.
Recall that Sodium (Na) is a highly reactive metal that tarnishes quickly and is not suitable for plating or trim.
Recognize that Neon (Ne) is a noble gas and does not form solid metals or plating materials.
Consider Sulfur (S), which is a nonmetal and does not have metallic properties or reflective appearance.
Identify Chromium (Cr) as a transition metal known for its excellent corrosion resistance and shiny, reflective surface, making it the common choice for car plating and trim.
