Table 1 shows the densities of some noble gases at room temperature and pressure (RTP).

Noble gasDensity at RTP in g/dm3\text{g/dm}^3g/dm3
Helium0.18
Neon0.90
Argon1.80
Krypton3.74

An incomplete bar chart showing the densities of noble gases: Helium, Neon, Argon, and Krypton. The y-axis is labeled 'Density at RTP in g/dm³' and ranges from 0.0 to 4.0 with major gridlines every 0.1 g/dm³. The x-axis lists the noble gases under four column positions. The bar for Helium is plotted at 0.18 g/dm³ and the bar for Krypton is plotted at 3.74 g/dm³. The slots for Neon and Argon are currently empty.

Complete the bar chart to show the densities of neon and argon.
