The model that should show the corresct representation of xenon gas is one in which the gas molecules are isolated and monoatomic.
<h3>What is a noble gas?</h3>
A noble gas is a member of group 18 of the periodic table. Noble gases are known not to interact with each other and occur as monoatomic particles.
The images are not shown here hence the question is incomplete. However, we do know that any of the models that show individual monoatomic particles is a representation of xenon gas.

The 2nd ionization energy is removing a 2nd electron from that resulting cation:
<span>Li+ --> Li2+ + 1e- </span>
Cold water<span> is </span>more dense<span> and will sink in room-temperature </span>water<span>. hope it helps :)</span>
