Chapter 18, Problem 1RQ

Solution

To determine: The electron-dot structures of elements in the same group in the periodic table have in common with each other.

Answer:

The overall valence electrons are basically common in electron-dot structures of elements in the identical group in the periodic table.

Explanation:

All the elements get allocated in periodic table in form of periods as well as groups. There are overall eighteen groups and each shows their own distinct chemical behavior.

In periodic table, the elements existing with identical count of valence electrons get placed in same group. As chemical nature as well as the reactivity both rely upon the overall count of valence electrons and thus each group possesses their own specific chemical nature due to their identical count of valence electrons.

Conclusion:

Therefore, the overall valence electrons are basically common in electron-dot structures of elements in the identical group in the periodic table.
