Which element has a greater ionization energy?
argon (18) or rubidium (37)

Argon

Explanation:

-Ionization energy is the energy that is required to remove an electron.

-Ionization energy increases as you go from left to right the periodic table and decreases as you go from top to bottom of the periodic table.

-The reason why argon has greater ionization energy is because it is very hard to remove as argon is a noble gases. We know noble gases are inactive because they are already stable. If you're stable, you are less likely to gain or lose electron.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
