Four elements W, X, Y and Z contain 8, 11, 9 and 17 protons per atom ...
Element X can’t form anions as the outermost orbit contains only 1 electron.the atom will rather lose this electron to complete its octet and will become a cation.

Four elements W, X, Y and Z contain 8, 11, 9 and 17 protons per atom ...
Understanding Anions
An anion is a negatively charged ion formed when an atom gains electrons. The ability of an element to form anions is largely influenced by its position in the periodic table, particularly its electronegativity and the number of valence electrons.
Elements and Their Proton Counts
- W: 8 protons (Oxygen)
- X: 11 protons (Sodium)
- Y: 9 protons (Fluorine)
- Z: 17 protons (Chlorine)
Analysis of Each Element
- Element W (Oxygen):
- Has 6 valence electrons.
- Can gain 2 electrons to achieve a stable octet.
- Can form anions (O^2-).
- Element X (Sodium):
- Has 1 valence electron.
- Tends to lose this electron to achieve stability.
- Cannot form anions; instead, it forms cations (Na^+).
- Element Y (Fluorine):
- Has 7 valence electrons.
- Can gain 1 electron to achieve a stable octet.
- Can form anions (F^-).
- Element Z (Chlorine):
- Has 7 valence electrons.
- Can gain 1 electron to achieve a stable octet.
- Can form anions (Cl^-).
Conclusion
Among the elements listed, Element X (Sodium) is the one that cannot form an anion because it prefers to lose its single valence electron, making it a cation instead. All other elements can gain electrons to form stable anions. Hence, the correct answer is option 'A'.
