Question

which one of these species is an ion?
a) nacl
b) b3+
c) he
d) 14c
e) none of these species is an ion.

Explanation:

An ion is an atom or molecule with a net electric charge due to the loss or gain of electrons.

• \( \text{NaCl} \) is a neutral compound (sodium chloride), not an ion.
• \( \text{He} \) is a neutral helium atom.
• \( 14\text{C} \) is a neutral carbon - 14 atom (isotope).
• \( \text{B}^{3 + } \) is a boron ion with a + 3 charge (it has lost 3 electrons).

Answer:

B. B³+
