Explanation:
X- are the non-valence or shielding electrons in an atom. They are the electrons in an atom which excludes the inner orbital ones.
The valence electrons are the electrons in the outermost shell of an atom.
Effective nuclear charge = Atomic number - Non-valence electrons.
- The non-valence electrons are located inside of the main/inner electronic shell.
- The valence electrons are located outside the main shell.
For example, Neon:
Atomic number = 10
Electronic configuration 1s² 2s² 2p⁶
Non-valence electrons = 1s² = 2 electrons
Valence electrons = 2s² 2p⁶ = 8 electrons
The trend of the non-valence electrons across the periodic table:
Down a group, new electronic shells are added, this implies that the non-valence electrons increases down the group.
Across the period, the number of the non-valence electrons stays the same because no additional electronic shells are added.

Answer: Option (C) is the correct answer.
Explanation:
Horticulture is the study of science related to the art of growing fruits, vegetables, or plants.
Therefore, when a person graduated from a college with a degree in horticulture then it means he has obtained enough knowledge about how to grow plants, fruits or vegetables in the best way possible.
Thus, Vincent who also graduated in horticulture cannot accurately tell about human psychology.
Hence, we can conclude that the statement this claim may not be accurate because the blog is produced by someone who is not an expert in the field of human psychology.
