Brass is an alloy of
Correct answer: C. Copper and Zinc
- A. Copper and Iron
- B. Copper and Mg
- C. Copper and Zinc
- D. Copper and Silver
Explanation
Brass is a binary alloy composed of copper (Cu) and zinc (Zn). The proportion of copper and zinc can vary, but it is typically a combination of 60-70% copper and 30-40% zinc. The addition of zinc to copper produces an alloy with improved strength, corrosion resistance, and ductility compared to pure copper.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
