Question

Four elements W, X, Y and Z contain 8, 11, 9 and 17 protons per atom respectively. The element which cannot form an anion is most likely to be (a) W
(b) X
(c) Y
(d) Z

Answer 1

Answer:

b X its valency is positive3

Explanation:

protons is equal to atomic number

Answer 2

Answer is Option (b)

Explanation:

• The element which cannot form an anion is most likely to be X.

• Element X cannot form anions as the outermost shell or orbit contains only one electron.  

• The Atom will rather lose this electron to complete its octet and will become a cation.

• Those with a negative charge are called anions and those with a positive charge are called cations.
• These opposing charges frequently result in ionic bonds with one another.
• An anion is an ion that carries a negative charge, causing it to migrate to the anode (positive electrode) in electrolysis
