Where is xenon located on the periodic table?
noble gases
xenon (Xe), chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds.
Why are elements placed where they are on the periodic table?
The chemical elements are arranged in order of increasing atomic number. Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency. An example of a group in the periodic table is the alkali metal group.
Where is xenon found and in what form?
Xenon is a trace gas found in the Earth’s atmosphere to the extent of about one part in 20 million, According to the Los Alamos National Laboratory. This makes it very rare. It is also found in Mars’ atmosphere at 0.08 ppm. This noble gas can also be found down on Earth.

Xenon/Discovered
Why is the periodic table not arranged by atomic mass?
Assuming there were errors in atomic masses, Mendeleev placed certain elements not in order of increasing atomic mass so that they could fit into the proper groups (similar elements have similar properties) of his periodic table. Elements were placed into groups that expressed similar chemical behavior.
Who found the element xenon?

Why do we need xenon?
Xenon is used in photographic flashes, in high pressure arc lamps for motion picture projection, and in high pressure arc lamps to produce ultraviolet light. It is used in instruments for radiation detection, e.g., neutron and X-ray counters and bubble chambers.
How many electrons are in xenon?
Except Helium (1s2) all the noble gases has 8 valence electrons (complete octet) and a electronic configuration of ns2 np6. So Xenon has eight electrons in outermost shell.
What family is neon in on the periodic table?
Neon is a member of the noble gas family. Other elements in this family includes helium, argon , krypton , xenon , and radon. These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases.
Where is xenon found naturally?
Xenon is a trace gas found in the Earth’s atmosphere to the extent of about one part in 20 million, According to the Los Alamos National Laboratory . This makes it very rare. It is also found in Mars’ atmosphere at 0.08 ppm. This noble gas can also be found down on Earth.
What is number ten on the periodic table?
Group 10, numbered by current IUPAC style, is the group of chemical elements in the periodic table that consists of nickel (Ni), palladium (Pd), platinum (Pt), and perhaps also the chemically uncharacterized darmstadtium (Ds). All are d-block transition metals.
