Helium atom has 2 electrons.
3
Sodium has 11 electrons.
13
Copper atom has 29 electrons.Uranium atom has 92 electrons.
A nitrogen atom has seven electrons.
inert gases
NONE!!!! There are 8 electrons in its outer energy shell. This completes its electron OCTET, thereby making it unreactive. Valence electrons are those which take part in combining the atom with another atom. Since Xenon is a Noble(Inert) gas it does not react with anything, thereby there are no valence electrons.
Helium atom has 2 electrons.
The atom must have 8 electrons to make it have a neutral charge
A Mercury atom has 80 electrons.
The number of electrons depends on what type of atom it is.
A germanium atom has 32 electrons.
normally 8
.p,om,
An atom of selenium has 34 electrons.
