Whether properties change or remain the same for elements across any period of the periodic table.
Answer to Problem 15RQ
No, the properties gradually change for elements across any period of the periodic table.
Explanation of Solution
A periodic table is a very systematic format discovered by scientists to study all the existing elements. It is designed so as to keep a glance at once of all elements present till date.
A periodic table has seven horizontal rows where the elements are placed according to their increasing number of electrons and are called periods. As the number of valence electrons changes their tendency to react with others also changes.
Thus, across the periods by increasing numbers of electrons the properties of the elements gradually changes and do not remains the same.
Conclusion:
Therefore, the properties gradually change for elements across any period of the periodic table.
