Which formula represents a mixture

The balanced redox reactions for the sequential reduction of vanadium are given below. reduction from + 5 to + 4: 2 VO2 + (aq) + 4 H + (aq) + Zn (s) → 2 VO2 + (aq) + Zn2 + (aq) + 2 H2O (l) reduction from + 4 to + 3: 2 VO2 + (aq) + Zn (s) + 4 H +

What do the numbers listed for an element on the periodic table represent? The smaller number is the number of protons, and the greater number is the mass. The smaller number is the number of neutrons, and the greater number is the number of protons.

Helium (He), oxygen (O), carbon (C) fluorine (F), and chlorine (Cl) are all nonmetals. Using the periodic table, which pair of nonmetals do you predict has the most similar properties, and why?
