Ответ:
The answer is C.
Explanation:
When hydrogen react with oxygen to form hydroxide ion, the electron in each element will add up together.
So 8-electrons of oxygen react with 1-electron of hygrogen to form 10-electrons of hydroxide.
In an element, atomic number(proton number) is equal to numbet of electrons.
