How many electrons in an atom could have a set of quantum numbers n=2? How many electrons in an atom could have a set of quantum numbers with n = 3? How many electrons in an atom could have a set of quantum numbers n=7, l=3, m_l=-1? How many electrons in an ...
A neutral atom is one that has an equal number of protons and electrons. The positive charge of the protons and the negative charge of the electrons will cancel each other out. In the case of argon, it has 18 protons and thus will be neutral if it has 18 electrons in total between ...

ONE ATOM SAYS TO ANOTHER: 'OH NO, I'VE lost an electron'. The other replies: 'Are you positive?' This classic science classroom joke explains how cations form. Neutral atoms have the same number of positively charged protons in their nucleus as negatively charged electrons in their shells....
In many materials, the electrons are tightly bound to the atoms. Wood, glass, plastic, ceramic, air, cotton -- these are all examples of materials in which electrons stick with their atoms. Because these atoms are so reluctant to share electrons, these materials can't conduct electricity ...
Photo: Inside an atom: electrons are the particles in shells (orbitals) around the nucleus (center).And the same goes for science. The smallest thing you can see with a microscope is determined (partly) by the light that shines through it. An ordinary light microscope uses photons of light...
