11. Climate researchers in Greenland can use ice core samples to tell them about carbon di the atmosphere in the past. The researchers have found an ice core sample that shows
a period when carbon dioxide in the atmosphere decreased. What happened to the amo

it means there are 3 atoms of oxygen

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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.
