what is xe in the periodic table?
481891
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. More than 4.5 times heavier than air, xenon is colourless, odourless, and tasteless.

XeOF4 - Xenon oxide tetrafluoride. Xe has 8 valence electrons plus 1 for each Xe-F single bond plus 2 for Xe=O.

In any event, you must start with Xe and 4 O atoms, and note that there are 8 + 4x6 = 32 total valence electrons. The Xe atom is attached to all four oxygen atoms. Four bonds = 8 electrons, so you have 24 electrons left.

The XeO3 molecule would be polar because it contains three polar Xe –O bonds that are asymmetrically arranged around the central Xe atom (i.e., the bond dipoles do not cancel but add to a net molecular dipole with the Xe atom at the positive end).

The group 18 elements include helium, neon, argon, krypton, xenon and radon. They are referred to as noble gases or inert gases. The general configuration of the valence shell is ns2np6. All of these elements occur in a free state in the atmosphere.

Xenon is one of the inert or noble gases and is odorless, colorless, tasteless and chemically non-reactive. While not toxic on its own, its compounds are strong oxidizing agents that are highly toxic.

Seventeen elements are generally classified as nonmetals: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

XeF2 is dsp3 hybridized and contains 3 lone pair and 2 bonding pairs of valence electrons around the Xenon.
650896
The extremely stable noble gasses, including helium, neon, argon, krypton, xenon and radon, are all also nonmetal covalent elements. These elements form bonds with one another by sharing electrons to form compounds.
232174
Xe has a complete filled 5p configuration. As a result when it undergoes bonding with an odd number (3 or 5) of F atoms it leaves behind one unpaired electron. This causes the molecule to become unstable. As a result XeF3 and XeF5 do not exist.
803522
A thallium atom has 81 electrons, arranged in the electron configuration [Xe]4f145d106s26p1; of these, the three outermost electrons in the sixth shell are valence electrons.
368432
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

Only the heavier noble gases like Xe, etc will react with oxygen and fluorine. noble gas form compounds with oxygen and fluorine only because they are most electronegative elements.
151489
Noble gas. The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold.
576344
Almost all known xenon compounds contain the electronegative atoms fluorine or oxygen. The oxidation state of xenon in its compounds is generally +2, +4, +6, or +8. ... XeF8 is not known to exist even though the oxidation state would be +8.

The Lewis structure for XeF4 has a total of 36 valence electrons. When we are done adding valence electrons we check each atom to see if it has an octet (full outer shell).
