Question

use what you learned from the readings to answer the question on the right. predict the charge on the monatomic ions formed from the following atoms in binary ionic compounds. write your answers in the format: 3+ i sr k

Explanation:

Step1: Determine the charge for iodine (I)

Iodine is in group 17 (halogen). Halogens gain 1 electron to achieve a stable electron configuration. So the charge is \(1-\).

Step2: Determine the charge for strontium (Sr)

Strontium is in group 2. Group 2 elements lose 2 electrons. So the charge is \(2+\).

Step3: Determine the charge for potassium (K)

Potassium is in group 1. Group 1 elements lose 1 electron. So the charge is \(1+\).

Answer:

\(1-\)
\(2+\)
\(1+\)
