question_answer 14)

            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 elements more easily                                    (d) The oxides become more acidic. 

Answer:

(c)The atoms lose their valence electrons with difficulty and not easily. This is on account of the reasons that nuclear charge increases from left to the right since the atomic number of the elements gradually increases with the increase in nuclear charge, the force binding the electrons with the nucleus increases.                                                                   Therefore, the atoms lose their valence electrons with difficulty.
