Question

Which of the following statements is (are) correct statement about the trends when going from left to right across the periods of 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

Answer: (A), (B), (D)

The correct options are
A The number of valence electrons increases
B The elements become less metallic in nature
D The oxides become more acidic

On moving along a period tendency to lose electrons decreases whereas the tendency to gain electron increases.
Therefore metallic character decreases, valence electrons increases and acidic nature of oxides increases.
