Explanation:

Step1: Identify cation and anion

For ionic compounds, name the cation first and then the anion.

Step2: Name compounds in part 1

a) Silver has a +1 charge and oxygen has a - 2 charge. The compound is silver oxide.
b) Potassium has a +1 charge and iodine has a -1 charge. The compound is potassium iodide.
c) Lithium has a +1 charge and chlorine has a -1 charge. The compound is lithium chloride.
d) Barium has a +2 charge and oxygen has a -2 charge. The compound is barium oxide.
e) Zinc has a +2 charge and fluorine has a -1 charge. The compound is zinc fluoride.
f) Magnesium has a +2 charge and phosphorus has a - 3 charge. The compound is magnesium phosphide.
g) Calcium has a +2 charge and bromine has a -1 charge. The compound is calcium bromide.
h) Sodium has a +1 charge and sulfur has a -2 charge. The compound is sodium sulfide.
i) Aluminum has a +3 charge and chlorine has a -1 charge. The compound is aluminum chloride.
j) Beryllium has a +2 charge and nitrogen has a -3 charge. The compound is beryllium nitride.

Step3: Write formulas in part 2

a) Beryllium has a +2 charge and sulfur has a -2 charge. The formula is BeS.
b) Lithium has a +1 charge and nitrogen has a -3 charge. The formula is Li₃N.
c) Zinc has a +2 charge and chlorine has a -1 charge. The formula is ZnCl₂.
d) Sodium has a +1 charge and bromine has a -1 charge. The formula is NaBr.
e) Calcium has a +2 charge and chlorine has a -1 charge. The formula is CaCl₂.
f) Magnesium has a +2 charge and oxygen has a -2 charge. The formula is MgO.
g) Silver has a +1 charge and iodine has a -1 charge. The formula is AgI.
h) Aluminum has a +3 charge and sulfur has a -2 charge. The formula is Al₂S₃.
i) Potassium has a +1 charge and fluorine has a -1 charge. The formula is KF.
j) Calcium has a +2 charge and phosphorus has a -3 charge. The formula is Ca₃P₂.

Step4: Complete part 3 table

a) Sodium (Na⁺) with chlorine (Cl⁻) forms NaCl (sodium chloride), with fluorine (F⁻) forms NaF (sodium fluoride), with oxygen (O²⁻) forms Na₂O (sodium oxide).
b) Magnesium (Mg²⁺) with chlorine (Cl⁻) forms MgCl₂ (magnesium chloride), with fluorine (F⁻) forms MgF₂ (magnesium fluoride), with oxygen (O²⁻) forms MgO (magnesium oxide).
c) Calcium (Ca²⁺) with chlorine (Cl⁻) forms CaCl₂ (calcium chloride), with fluorine (F⁻) forms CaF₂ (calcium fluoride), with oxygen (O²⁻) forms CaO (calcium oxide).
