Question

A cation carries positive charge due to _______ .

• A. loss of electron(s)
• B. gain of electron(s)
• C. gain of proton(s)
• D. None of the above

Answer 1

The correct option is A loss of electron(s)

A cation carries positive charge due to loss of electron(s). Thus, sodium loses an electron to form sodium cation. Sodium cation has unit positive charge.
$Na\to N{a}^{+}+e^{-}$

An anion carries negative charge due to gain of electron(s). Thus chlorine gains an electron to form chloride ion. Chloride ion has unit negative charge.
$Cl+e^{-}\to C{l}^{-}$
