Which of the following statements is not...

Which of the following statements is not a 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.

Text Solution

Verified by Experts

The correct Answer is:
C
Explanation : The atoms lose their electrons more easily. Because on moving from left to right across the periods of the periodic table, the non-metallic character increases. Hence, the tendency to lose electrons decreases.
