C
O, Si, Al, Fe, Ca, Na, K, Mg
D
O, C, N, H, S, Cl, P, F
Verified step by step guidance1
Understand that the problem asks for the eight most abundant elements in Earth's crust, which is a question about elemental composition rather than calculations.
Recall that Earth's crust is primarily composed of oxygen (O) and silicon (Si), followed by elements like aluminum (Al), iron (Fe), calcium (Ca), sodium (Na), potassium (K), and magnesium (Mg).
Recognize that elements such as copper (Cu), zinc (Zn), lead (Pb), mercury (Hg), silver (Ag), and gold (Au) are much less abundant in the crust and are considered trace elements.
Note that elements like carbon (C), nitrogen (N), hydrogen (H), sulfur (S), chlorine (Cl), phosphorus (P), and fluorine (F) are more abundant in the atmosphere or biosphere but not among the top eight in the crust.
Conclude that the correct list of the eight most abundant elements in Earth's crust is: O, Si, Al, Fe, Ca, Na, K, and Mg.
