Is a phone physics or chemistry

Physics

Explanation: Cellphones emit electromagnetic radiation and contain compact antennas. Cell phones communicate through radiofrequency waves which are a form of energy in the electromagnetic spectrum. These waves are located between FM radio waves and microwaves, which are results you can only obtain by experimenting with Physics, not chemistry.

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.
