which element will form an ionic bond with lithium, li? magnesium, mg calcium, ca cesium, cs iodine, i
Answer
Brief Explanations:
Ionic bonds typically form between a metal and a nonmetal. Metals tend to lose electrons to form positive ions (cations), while nonmetals tend to gain electrons to form negative ions (anions). Lithium (Li) is an alkali metal (Group 1) and readily loses one electron to form the Li⁺ cation. We need to find a nonmetal among the options that will accept an electron to form an anion.
- Magnesium (Mg) and Calcium (Ca) are alkaline earth metals (Group 2).
- Cesium (Cs) is an alkali metal (Group 1). Metals do not typically form ionic bonds with other metals.
- Iodine (I) is a halogen (Group 17), which is a nonmetal. Halogens readily gain one electron to form a negative ion (anion), in this case, I⁻. Therefore, lithium (metal) will form an ionic bond with iodine (nonmetal) through the electrostatic attraction between Li⁺ and I⁻ ions, forming lithium iodide (LiI).
Answer:
iodine, I
