Question

question 3: which of the following species, species (i) or (iii) shown in the table below, is an anion? a. species (i) b. species (iii) species protons electrons (i) 74 72 (iii) 52 54

Explanation:

Step1: Recall anion definition

An anion has more electrons than protons.

Step2: Analyze Species (i)

For Species (i), protons = 74, electrons = 72. Since 72 < 74, it is not an anion.

Step3: Analyze Species (iii)

For Species (iii), protons = 52, electrons = 54. Since 54>52, it is an anion.

Answer:

B. Species (iii)
