First you need to know how ionic compounds are created!

Ionic compounds are formed by IONS (Obviously, what am I, a dummy?) 
There are two types of ions: anions and cations.
Anions can only be formed by nonmetals, and cations can only be formed by metals.
In order for ions to bond, there must be one anion and one cation, because opposite charges attract.

Let's look at your choices.

1) Ca + Br can form ionic bonds
2) Na + F can form ionic bonds
3) Li + Cl can form ionic bonds

However...

4) Mg + Ar

This is a special case. Ar is a NOBLE GAS, which means that it has the maximum number of valence electrons (8) in its outermost shell. Therefore, ANY type of bonding is IMPOSSIBLE.

Your answer should be 4) Mg + Ar

What does electronegativity measure
Rainbow [258]
Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

The pressure on 2.50 L of gas is changed from 4.5 atm to 2.2 atm. What is the new volume of gas?
swat32

Answer:

<h2>5.11 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{2.5 \times 4.5}{2.2}  =  \frac{11.25}{2.2}  \\  = 5.1136666...

We have the final answer as

<h3>5.11 L</h3>

Hope this helps you
