Which of the following statement is not correct about the trends when ...
The correct option is C.
The characteristic chemical property of a metal atom is to lose one or more of its electrons to form a positive ion. However, certain metals lose electrons much more readily than others. In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li).

Which of the following statement is not correct about the trends when ...
Explanation:
Valence electrons:
- The number of valence electrons increases as you go from left to right across the periodic table.
- Valence electrons are the electrons in the outermost shell of an atom, and they determine the chemical properties of an element.
Metallic nature:
- Elements become less metallic in nature as you move from left to right.
- This is because the number of valence electrons increases, making it harder for the atoms to lose electrons and exhibit metallic properties.
Electron loss:
- The statement that atoms lose their electrons more easily as you move from left to right is not correct.
- In fact, as you move from left to right, the atoms tend to gain electrons rather than lose them.
- This is because the elements on the right side of the periodic table are nonmetals, and they have a higher electronegativity, making it easier for them to gain electrons.
Acidity of oxides:
- The oxides become more acidic as you move from left to right across the periodic table.
- This is because the elements on the right side of the periodic table tend to form oxides that react with water to produce acidic solutions.
Valence electrons:
- The number of valence electrons increases as you go from left to right across the periodic table.
- Valence electrons are the electrons in the outermost shell of an atom, and they determine the chemical properties of an element.
Metallic nature:
- Elements become less metallic in nature as you move from left to right.
- This is because the number of valence electrons increases, making it harder for the atoms to lose electrons and exhibit metallic properties.
