Vedclass · Answer

(C) Moving from left to right across a period in the Periodic Table: $1$. The metallic character of elements decreases because the nuclear charge increases,making it harder to lose electrons. $2$. The number of valence electrons increases from $1$ to $8$. $3$. Since the nuclear charge increases and the atomic size decreases,the effective nuclear attraction on valence electrons increases,making it harder for atoms to lose electrons. Thus,the tendency to lose electrons decreases. $4$. The oxides of elements on the left are basic,while those on the right are acidic. Therefore,the statement that 'atoms lose their electrons more easily' is incorrect.

Which of the following statements is not correct regarding the trends observed when moving from left to right across the periods of the Periodic Table?
