Question
For each of the following ions, indicate the number of protons and electrons the ion contains.a. $\mathrm{Ba}^{2+}$b. $\mathrm{Zn}^{2+}$c. $\mathrm{N}^{3-}$d. $\mathrm{Rb}^{+}$e. $\mathrm{Co}^{3+}$f. $\mathrm{Te}^{2-}$g. $\mathrm{Br}^{-}$
Step 1
$\mathrm{Ba}^{2+}$: Barium (Ba) has an atomic number of 56, which means it has 56 protons. Since it has a 2+ charge, it has lost 2 electrons. Show more…
