complete the table below. for example, in the first row decide whether sc³⁺ is a cation or anion. in the second row, write the symbol for the ion that an atom of strontium is mostly likely to form and then decide what type of ion it is.\n\n| element | most likely ion |\n| ---- | ---- |\n| | symbol of ion | type of ion |\n| scandium | sc³⁺ | cation anion |\n| strontium | | cation anion |\n| iodine | | cation anion |\n| phosphorus | | cation anion |\n| cesium | | cation anion |
Answer
Explanation:
Step1: Determine strontium ion
Strontium is in group 2, it loses 2 electrons to form $Sr^{2 +}$, a cation.
Step2: Determine iodine ion
Iodine is in group 17, it gains 1 electron to form $I^{-}$, an anion.
Step3: Determine phosphorus ion
Phosphorus is in group 15, it gains 3 electrons to form $P^{3 -}$, an anion.
Step4: Determine cesium ion
Cesium is in group 1, it loses 1 electron to form $Cs^{+}$, a cation.
Answer:
| element | most likely ion | |
|---|---|---|
| symbol of ion | type of ion | |
| scandium | $Sc^{3+}$ | cation |
| strontium | $Sr^{2+}$ | cation |
| iodine | $I^{-}$ | anion |
| phosphorus | $P^{3 -}$ | anion |
| cesium | $Cs^{+}$ | cation |
