A spherical electron cloud surrounding an atomic nucleus would best represent an s orbital. A maximum of 2 electrons can occupy an orbital.
in 5s it is filled but in 4d or 4s its half

Electrons enter the orbitals on the basis of increasing energy of sub-shells. Also, when an electron occupies an orbital another electron cannot occupy that orbital until all other orbitals of that sub-shell have atleast 1 electron.
How many atoms / electron clouds does helium have ?

An electron in a 2s orbital is on average closer to the nucleus.
of course they can. They have to be of opposite spin and two is the maximum number that can occupy one orbital.
there r 2 electrons in the s orbital, their r 6 electrons in p orbital , their r 10 electron's in the d orbital and 14 electrons in f orbital.
Fluorine in its elemental stage has 1 unpaired electron. ( 2p5 orbital has one unpaired electron in 2p orbital)
The specific orbital the electron is in
An electron pair are two electrons which occupy the same orbital in an atom or molecule. Paired electrons are represented by two dots.
