Answer:

The correct answer is "the 3rd electron".

Explanation:

The ionization energy is defined as the minimum quantity of energy that an electron requires to be removed from an atom at a defined moment. In the case of sodium, is widely known that the most common ion found in nature is Na+. This is explained because the 1st electron is the one that requires less ionization energy. Among the 1st, 2nd and 3rd electrons, the one that requires more ionization energy is the 3rd, because it represents the sum of the 1st and the 2nd. I attached a table as reference.

Stella [2.4K]

It is important to make the client understand that while alcohol might not be the cause of their problems or all of their problems it does affect the process of their decision making depending on the situation and how they feel towards different situations. A short-term goal would be to go a week without drinking alcohol and to note their changes in mood, behavior towards others and different challenges that they face. Another option is to set a "challenge" to see how long the client can go without the consumption of alcohol, the longer they go without the bigger the changes they will see in their day to day life.
