such substances are not attracted towards magnet and are known as Diamagnetic substances.
Many hydrocarbons have no unpaired electrons, which is why most of them are non-polar.
Diamagnetic. All of the electrons 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.

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.
All of the electrons are paired. If you are asking how many lone pairs, there are 4.
two electrons are paired means two electrons are bonded
Diamagnetic. All of the electrons are paired.
A molecule is diamagnetic, if all the electrons are paired.
An electron pair are two electrons which occupy the same orbital in an atom or molecule. Paired electrons are represented by two dots.
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.

Any atom with unpaired electrons in it's orbital exhibits paramagnetism, that is that it will be attracted into an inducing magnetic field. Phosphorous has 15 electrons: 1s>2e-(all paired) 2s>2e- 2p>6e-(all paired) 3s>2e-(these two are paired) 3p>3e-(note that these are the unpaired electrons that cause it to be paramagnetic) All this is because a moving negative charge produces a magnetic field if there are two electrons in the same orbital they always spin in opposite directions cancelling each other out. When there are unpaired electrons that creates the magnetic field.

There are 4

Such elements include Noble gases and elements of II A group of periodic table.
