There are 54 electrons, 54 protons, and 78 neutrons in an atom of 132 Xe.54.
Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colourless, dense, odourless noble gas found in Earth's atmosphere in trace amounts.
Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized.
Solid xenon changes from face-centred cubic (fcc) to hexagonal close packed (hcp) crystal phase under pressure and begins to turn metallic at about 140 GPa, with no noticeable volume change in the hcp phase. It is completely metallic at 155 GPa.
When metallized, xenon appears sky blue because it absorbs red light and transmits other visible frequencies. Such behaviour is unusual for a metal and is explained by the relatively small width of the electron bands in that state.

Answer:
The answer is
<h2>2.64 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 611 g
volume = final volume of water - initial volume of water
volume = 256.7 - 25.1 = 231.6 mL
The density of the metal is
We have the final answer as
<h3>2.64 g/mL</h3>
