The statement that is not correct about the trends in the properties of the elements of a period on going from left to right is: "The atoms lose their electrons more easily."

Here's why:

1. "The atoms lose their electrons more easily" - This is incorrect. As we move from left to right across a period, the atomic size decreases due to an increase in nuclear charge. This makes it harder for atoms to lose their electrons, not easier.

2. "There is an increase in the number of valence electrons" - This is correct. As we move from left to right across a period, the number of valence electrons increases.

3. "The oxides become more acidic" - This is correct. As we move from left to right across a period, the nature of oxides changes from basic to acidic.

4. "The elements become less metallic" - This is correct. As we move from left to right across a period, the metallic character of the elements decreases.
