Ionic compounds are formed by a positive ion called cation and a negative ion called anion.
I will show you some examples:
NaCl is formed by the cation Na+ and the anion Cl -
CaF2 is formed by the cation Ca 2+ and the anion F -
Li2O if formd by the cation Li + and the anion O 2-.
To tell that you use the oxidation number of each element. I did it this way
Ca F2 => Ca has oxidation number 2+ and F has oxidation number 1- then the ions have that very same charge number.
b) It is based on atomic properties as alkali metals requires 7 more electrons to complete their outer orbit. And they try to give those electrons to other elements to obtain noble gas configuration.
Noble gases are the gases which do not react easily with anything. They are also called as Inert gases, and belongs to group 18 of the periodic table.
Alkali metals are the substances which are found in Group I of a periodic table. Mostly the elements which are present are:
Properties of alkali metals are: Soft, shiny reactive metals. They are soft enough to cut with knife. Metals react with water and air quickly and gets tarnish, so pure metals are stored in container by dipping them in oil to prevent oxidation.

Answer:
Well, Aluminum Oxide has a very high melting point. Carbon dioxide has a very low boiling point.
Explanation:
They are both talking about different things, melting and boiling. Aluminum Oxide's melting point is much higher then carbon dioxide's melting point. Hope this help, and good luck on your assignment (if one)
Answer:
The amount of C2H4I2 produced is maximized if
-Adding C2H4 to the reaction mixture
-Decreasing the reaction volume
-Also can include: raising the reaction temperature
