With the development of petawatt (10 15 watt) lasers, it is now possible to split atoms by using laser light to excite electrons in metals encasing a radioactive substance. Similarly, you could use a 50 terawatt (5 x 10 12 watt) laser to excite the electrons in the metal. [9] 3. Web14 de nov. de 2014 · Understanding the Atom The nucleus of an atom is surround by electrons that occupy shells, or orbitals of varying energy levels. The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. There is also a maximum energy that each electron can have and still be part of its atom.

Web$\begingroup$ @DanDascalescu, but yes, I'd say they are being very confusing with that question and the several that follow it: by the logic that they call the electron cloud "empty" they could also call the proton "empty" since it's actually made up of quarks. If you're going to say an atom is 99.999999% empty, you should just say "all of space is empty". simplicity boys patternsWebJust how small are atoms? And what's inside them?
