(20 13? Puyang Yimei) X, Y, Z, W and Q are five short-period main group elements with increasing atomic numbers, of which only Z is metal and W is yellow.
Short-period main group elements. Among them, only Z is a metal, and the simple substance of W is a yellow solid, so W is S. From the relative positions of X, Y and W in the periodic table of elements, Y is O, X is C, and X, Y, Z, W and Q are increasing atomic numbers, so Q is Cl, and Z may be one of Na, Mg and al.

A among the five elements, the largest atomic radius is Z, so A is wrong;

B. The weaker the oxidation of simple substance, the stronger the reducibility of corresponding ions, so the simple anion of Y is weaker than that of W, so B is wrong;

The compound formed by C, Y and Z is a metal oxide, which can react with hydrochloric acid, so C is correct;

D. if z is Na, the compound NaCl aqueous solution formed by z and q is neutral, so d is wrong;

So choose C.
