Problem 59E

What are the possible values of  for each value of n?

a. 1                 b. 2                 c. 3                 d. 4

Step-by-Step Solution:

Soution Step 1 The given statement is: "Since elements that form cations are metals and elements that form anions are nonmetals, elements that do not form ions are metalloids." I disagree with the statement because the last part of the sentence is wrong. Metalloids are found to form ions. Explanation The first part of the sentence says that the elements that form cations are metals ,which is a true statement. Stronger metal atoms like 1st and 2nd group elements are bigger in size. Hence they are highly electropositive with low ionization potentials and tend to lose electrons easily forming cations. The second part of the sentence is also true since non metals have high electron affinities and thus a greater tendency to form anions. The last part of the sentence which says that elements that do not form ions are metalloids is wrong. Metalloids have properties intermediate between metals and non-metals. The most commonly known non metals are boron, silicon, germanium, arsenic and antimony. They do 4+ 2+ 4+ 3+ form ions like Si ,Ge ,Ge ,Sb etc...
