If you were asked to describe metals and magnetism you could say. a. non–paired electrons spin in opposite directions in all metals, creating a magnetic field. b. metals are magnets because they have more electrons than non–magnetic materials. c. metals can become magnetic if they have many spinning electrons that create magnetic fields. d. the electrons in some metals pair up to create a magnetic field.

Answer : Option D) the electrons in some metals pair up to create a magnetic field.

Explanation : Most of the metals are magnetic in nature including some exceptions. When the unpaired electrons get aligned with the magnetic field they posses magnetism. Also there are some paired electrons in metals which align themselves according to the magnetic field and create magnetism in them.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

i think its 100

i hope this !
