Question

Which of the following statements is not a correct statement about the trends when going from left to right across the periods of the Periodic Table.

• A. The elements become less metallic in nature.
• B. The number of valence electrons increases.
• C. The atoms lose their electrons more easily.
• D. The oxides become more acidic.

Answer 1

The correct option is C

The atoms lose their electrons more easily.

Explanation for the incorrect option:

(C) The atoms lose their electrons more easily.

• The tendency of the elements to lose electrons reduces and the tendency of them to gain electrons grows as we move across the periods of the Periodic Table from left to right.
• Therefore, across the periods, non-metallic properties rise and metallic characteristics fall.
• Thus, it becomes more challenging to remove electrons from the elements.

Explanation for the correct options:

(A) The elements become less metallic in nature.

• Metallic properties of the elements diminish from left to right across the periods, whereas non-metallic properties increase.

(B) The number of valence electrons increases.

• The size of the elements grows from left to right across the periods, and consequently, the number of valence electrons grows as well.

(D) The oxides become more acidic.

• In the elements, the tendency to lose electrons declines, and the tendency to gain electrons rises from left to right across the periods of the Periodic Table.
• As a result, oxides become more acidic.

Hence, option (C) is not correct., the atoms lose their electrons more easily is not a correct statement about the trends when going from left to right across the periods of the Periodic Table.
