Question

Which of the following is true in regard to ions? A. A cation will hold a positive charge if it gains one or more electrons. B. An ionized atom has a number of protons that is unequal to the number of electrons. C. Ions can carry only positive charges. D. Losing one or more electrons will turn an atom into an anion.

Answer 1

Answer:

B. An ionized atom has a number of protons that is unequal to the number of electrons.

Explanation:

For a neutral atom , the number of proton and electron is equal. An ionized atom has either loss or gain electron, thereby making the number of proton and electron unequal. The answer B is true because an ionized atom has either loss or gain electron to make the number of electron and proton unequal.

Option A is incorrect because a cations holds a positive charge when it loss one or more electron not when it gains one or more electron(s). Anions possess negative charge for gaining electron(s).

Option C is not true because ions can also carry negative charges and they are called anions.

Option D is false because losing one or more electron will turn an atom to a cations.
