Question

"When an electron is removed from a sodium atom ($\mathrm{Na}$), sodium ion (${\mathrm{Na}}^{+}$) is formed". Is this statement correct? If not, correct it.

Answer 1

• Cations are the positively charged species that are formed by the loss of electrons by any element or molecule. Example, Sodium ion (${\mathrm{Na}}^{+}$) is the cation formed by the loss of one electron (${\mathrm{e}}^{-}$) from the Sodium atom ($\mathrm{Na}$).
• $\mathrm{Na}\to {\mathrm{Na}}^{+}+{\mathrm{e}}^{-}$
• Thus, when an electron is removed from a Sodium atom ($\mathrm{Na}$), Sodium ion (${\mathrm{Na}}^{+}$) is formed.
• Hence, the statement is correct.
