Question

group 1 metals can bond with group 16 nonmetals to form ionic compounds. an example is sodium sulfide, which is used to break down wood chips into wood pulp to make paper. complete the statement. to produce a neutral ionic compound, one ion from group 16 is needed for every ion(s) from group 1. show periodic table

Explanation:

Step1: Determine the charge of group 1 ions

Group 1 metals (e.g., Na) form ions with a charge of \(+1\).

Step2: Determine the charge of group 16 ions

Group 16 non - metals (e.g., S) form ions with a charge of \(-2\).

Step3: Calculate the ratio of ions

Let the number of group 1 ions be \(x\) and group 16 ions be \(y\). For a neutral compound, the sum of charges is zero. So, \(x\times(+ 1)+y\times(-2)=0\). If \(y = 1\) (one group 16 ion), then \(x\times(+1)-2 = 0\), which gives \(x = 2\).

Answer:

\(2\)
