There are ______ electrons, _______ protons, and ______ neutrons in an atom of .
Georgia [21]

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.

You are given 600 grams of sodium chloride (NaCl), but you are planning to purify the substance and extract just the sodium. How
Eddi Din [679]

Answer:

236.02 grams of Na is produced by 600g of NaCl.

Explanation:

NaCl --> Na+Cl-

to find the number of moles NaCl has, divide the grams over the molar mass which is 600/58.44

number of moles of nacl= 10.2 moles

then turn moles back to grams which is moles x molar mass

10.2 moles x 22.9 mass

= 236.02 grams
