Which element is commonly used for the shiny trim and plating on cars due to its high luster and corrosion resistance?
A
Neon (Ne)
B
Sulfur (S)
C
Chromium (Cr)
D
Sodium (Na)
Verified step by step guidance1
Identify the key properties required for the element used in shiny trim and plating on cars: high luster (a shiny appearance) and corrosion resistance (ability to resist rust and degradation).
Recall that Neon (Ne) is a noble gas and chemically inert, so it is not used for plating or trim.
Consider Sulfur (S), which is a non-metal and tends to form compounds rather than metallic coatings; it is not suitable for shiny plating.
Sodium (Na) is a highly reactive metal that tarnishes quickly and is not used for plating or trim on cars.
Chromium (Cr) is a transition metal known for its bright, shiny finish and excellent corrosion resistance, making it the common choice for car trim and plating.
