'What is 'xe' ???
If you mean 'Xe' (Xenon), then it is monatomic.
It is listed in the Periodiuc Table in the Noble(Inert) gases Group.
NB When writing chemical symbols. One letter symbols are ALWAYS a CAPITAL letter. Two letter symbols are , first letter is a CAPITAL letter and the second letter is lower/small case. This is the agreed international standard.
Hence Xenon is 'Xe' ; NOT 'xe'.
All noble gases are monatomic and exist as individual atoms.
The noble gas electron configuration for barium is [Xe] 6s2.
The noble gas configuration for Lanthanum is [Xe] 5d1 6s2. Lanthanum has 57 electrons, so the noble gas before it (Xenon - atomic number 54) has a configuration of [Xe].
The electron configuration of polonium is: [Xe]6s24f145d106p4.
The noble gas electron configuration of radon is [Xe]4f145d106s26p6.
All noble gases are monatomic and exist as individual atoms.
no, Xenon is a noble gas so it has a full valence shell
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
The noble gas electron configuration for barium is [Xe] 6s2.
The noble gas configuration for Lanthanum is [Xe] 5d1 6s2. Lanthanum has 57 electrons, so the noble gas before it (Xenon - atomic number 54) has a configuration of [Xe].
The electron configuration of polonium is: [Xe]6s24f145d106p4.
The noble gas electron configuration of radon is [Xe]4f145d106s26p6.
All noble gases are mono atomic at room temperature
