Which best represents how electrons are arranged in the energy shells of a carbon atom? (hint, draw a Bohr model) *
first energy shell = 1 electron second energy shell = 5 electrons
first energy shell = 2 electrons second energy shell = 4 electrons
first energy shell = 3 electrons second energy shell = 3 electrons
first energy shell = 2 electrons second energy shell = 2 electrons

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

What is the major limitation to the light microscope?

The energy produced as a result of this flow of electrons from atom to atom is called
