Which of the following is the correct electron dot structure for a hydroxide ion?

A

Explanation:

A hydroxide ion is given as:

       OH⁻

The electron dot notation shows only the chemical symbol of the element surrounded by dots to represent the valence electrons. The chemical symbol denotes the nucleus and all electrons except the valence electrons.

The dots are arranged on the four sides in pairs.

Oxygen is made up of 6 valence electrons, and since the ion has a net negative charge, the hydrogen and oxygen achieved their stable configuration this way.

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
