The compound KF is an ionic compound. What are the ions of which it is composed?<\/p>\n\n\n\n
The compound ZnIz is an ionic compound. What are the ions of which it is composed?<\/p>\n\n\n\n
The compound CuCO, is an ionic compound. What are the ions of which it is composed?<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n
The three compounds you mentioned\u2014KF, ZnI2, and CuCO3\u2014are all ionic compounds. Here’s an explanation of the ions they are composed of:<\/p>\n\n\n\n
Potassium fluoride is an ionic compound formed from potassium (K) and fluorine (F). Potassium, a Group 1 alkali metal, has one valence electron, which it loses to achieve a stable electron configuration, forming a K\u207a ion<\/strong>. Fluorine, a Group 17 halogen, needs one electron to complete its valence shell, so it gains an electron, forming an F\u207b ion<\/strong>. Therefore, the ions in potassium fluoride are:<\/p>\n\n\n\n
\n
K\u207a (Potassium ion)<\/strong>: The potassium ion is positively charged because it loses an electron.<\/li>\n\n\n\n
F\u207b (Fluoride ion)<\/strong>: The fluoride ion is negatively charged because it gains an electron.<\/li>\n<\/ul>\n\n\n\n
2. ZnI2 (Zinc Iodide)<\/strong><\/h3>\n\n\n\n
Zinc iodide consists of zinc (Zn) and iodine (I). Zinc, a Group 12 transition metal, typically forms a Zn\u00b2\u207a ion<\/strong> by losing two electrons. Iodine, a halogen, gains one electron to form an I\u207b ion<\/strong>. Since there are two iodide ions needed to balance the charge from one zinc ion, the formula ZnI2 indicates that:<\/p>\n\n\n\n
\n
Zn\u00b2\u207a (Zinc ion)<\/strong>: The zinc ion has a +2 charge because it loses two electrons.<\/li>\n\n\n\n
I\u207b (Iodide ion)<\/strong>: Each iodide ion carries a negative charge.<\/li>\n<\/ul>\n\n\n\n
Copper carbonate is composed of copper (Cu), carbon (C), and oxygen (O). Copper can form either Cu\u207a<\/strong> (Copper(I)) or Cu\u00b2\u207a<\/strong> (Copper(II)) ions, depending on the oxidation state. In copper carbonate, copper typically forms a Cu\u00b2\u207a ion<\/strong>. Carbonate (CO\u2083) is a polyatomic ion with a 2\u207b<\/strong> charge. Therefore, the ions in copper carbonate are:<\/p>\n\n\n\n
\n
Cu\u00b2\u207a (Copper(II) ion)<\/strong>: The copper ion in this compound has a +2 charge.<\/li>\n\n\n\n
CO\u2083\u00b2\u207b (Carbonate ion)<\/strong>: The carbonate ion has a -2 charge.<\/li>\n<\/ul>\n\n\n\n
In summary:<\/p>\n\n\n\n
\n
KF is composed of K\u207a<\/strong> and F\u207b<\/strong>.<\/li>\n\n\n\n
ZnI2 is composed of Zn\u00b2\u207a<\/strong> and I\u207b<\/strong>.<\/li>\n\n\n\n
CuCO3 is composed of Cu\u00b2\u207a<\/strong> and CO\u2083\u00b2\u207b<\/strong>.<\/li>\n<\/ul>\n\n\n\n
Let me generate a visual representation of these ions.<\/p>\n\n\n\n
Here is the educational diagram showing the ionic compounds KF, ZnI2, and CuCO3, along with the corresponding ions. You can see the K\u207a and F\u207b ions for KF, Zn\u00b2\u207a and I\u207b for ZnI2, and Cu\u00b2\u207a and CO\u2083\u00b2\u207b for CuCO3.
