Periodic classification of Elements – Solutions

Which of the following statements is not a correct statement about the trends when

1. Going from left to right across the periods of periodic Table
2. The elements
3. The number of valence electrons increases.
4. The atoms lose their electrons more easily.
5. The oxides become more acidic.

Solution:

As we move from left to right along a period in a periodic table, the elements tend to be less metallic in nature, valence electrons increase gradually, the oxides become more acidic in nature and the atoms gain electrons to attain stable configuration. Hence, the incorrect statement is “The atoms lose their electrons more easily”.

Become less metallic in nature.

Correct answer: C.
