Question

Which of the following statement is not correct about the trends when going from left to right across 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 correct option:

(C) The atoms lose their electrons more easily:

• As one moves from left to right across a period, the metallic nature decreases.
• The metallic character decreases while the non-metallic character increases.
• The statement that atoms lose their electrons more easily is incorrect since the periodic table's non-metallic character increases as it moves from left to right across the periods. Elements tend to accept electrons. They do not lose electrons readily.

Hence, (C) is the correct option.

Explanation for the incorrect options:

(A) According to the modern periodic table, an element's metallic character decreases as one goes left to right across a period.

(B) The number of valence electrons increases as one moves from left to right across a period.

(D) The basic character of oxides decreases and the acidic nature of oxides increases across a period when one goes from left to right.

Therefore, the correct option is (C). The atoms lose their electrons more easily.
