An electron pair are two electrons which occupy the same orbital in an atom or molecule. Paired electrons are represented by two dots.
Lewis dot formula
These would be the elements in group 16. The elements in group 16 have six valence electrons. Those valence electrons are represented in a Lewis diagram by surrounding them with six dots. When drawing a diagram for an element with six valence electrons, there should be two pairs of dots (four total), and two separate dots.
two electrons are paired means two electrons are bonded
They can be both. In sodium there is a single unpaired valence electron. In magnesium there are two valence electrons and they are paired.
No. It is represented by an e- :)

Bismuth has five valence electrons, hence, it can be represented as a combination of Bi and five dots. There's considerable variation in the arrangement of these dots in Lewis diagrams.
the dots are the number of electrons in an elements valance shell (last shell). if it has no dots, it means it has lended its electrons to another element to become stable like its nearest noble gas.
they are the electrons in the outer shell of the atom(valence electrons)
They can be both. In sodium there is a single unpaired valence electron. In magnesium there are two valence electrons and they are paired.
First make the m.o (molecular orbital) diagram. If the electrons are paired in an orbital then it is diamagnetic . If the electrons are not paired then it is paramagnetic.
9
it has 6
someone correct me if im wrong, but i think its electrons that are not used in the bonding of molecules, shown as 2 dots (or crosses, whatever you use) attached with a sort of bubble to the body of the molecule. Only 2 electrons are paired and in a bubble. hope that sorta helped =)
I wouldn't say they are 'more significant' but if they are paired their magnetic moments cancel each other out and if they are not paired there is a net magnetic moment.
