Question

# Which of the following ions are likely to be found in chemical compounds: $\mathrm{Na}^{2+}, \mathrm{Li}^{+}, \mathrm{Al}^{4+}, \mathrm{F}^{2-}$, or $\mathrm{Te}^{2-}$ ? Explain briefly.

Solutions

Verified
Ion which is likely to be found in chemical compounds is $Li^+$. Lithium is directly above Sodium in the Group One Elements, the alkali metals and it has plus one change. $Li^+$ needs to gain one electron to form a compound and that is why will most likely form a compound. Other given ions need to lose or gain more than one electron to form a compound.
