Question

A Potassium ion has a positive charge.

• A. True
• B. False

Answer 1

The correct option is A True

Formation of Potassium ion:

1. The atomic number of Potassium $\mathbf{\left(}\mathbf{K}\mathbf{\right)}$ is $19$.
2. The electronic configuration of Potassium is $(2,8,8,1)$.
3. The outermost shell of Potassium atom has $1$ electron.
4. To have eight electrons in the outermost shell i.e. to complete its octet, Potassium atom loses $1$ electron.
5. On losing one electron, Potassium atom gains one positive charge and forms a Potassium ion $\mathbf{\left(}{\mathbf{K}}^{\mathbf{+}}\mathbf{\right)}$.
6. The reaction is: $\mathrm{K}\to {\mathrm{K}}^{+}+{\mathrm{e}}^{-}$
7. Thus, Potassium ion has a positive charge.

Therefore, the given statement is true.
