Question

write the charge of each ion in the compound below. kclo3 k = clo3 = write the name for the formula below.

Explanation:

Step1: Analyze the potassium ion ($K$)

Potassium ($K$) is in Group 1 of the periodic table. Elements in Group 1 tend to lose one electron to form ions. So, the charge of the potassium ion is $+1$.

Step2: Analyze the chlorate ion ($ClO_3$)

Since the compound $KClO_3$ is neutral (overall charge of 0) and the charge of $K$ is $+1$, the charge of the $ClO_3$ ion must be $-1$ to balance the $+1$ charge of $K$.

Step3: Name the compound

The compound $KClO_3$ is named potassium chlorate. The naming of ionic compounds follows the rule of stating the cation (potassium) first and then the anion (chlorate).

Answer:

$K = +1$; $ClO_3=-1$; Name: potassium chlorate
