A team of scientists from Goethe University Frankfurt, University of Marburg and Stockholm University have elucidated an ancient mechanism of ...

After the second level has 8 electrons, the next electron goes into the third level. 3rd Period: Sodium to argon—Electrons go into the third energy level. After the third energy level has 8 electrons, ...

In a new study, researchers from the Massachusetts Institute of Technology (MIT) used a cloud of ultracold sodium atoms to ...

For example, the atomic number of sodium is 11. Every sodium atom has 11 protons and 11 electrons. It has 11 positive charges and 11 negative charges. The mass number of an atom is its total ...

To create a metal plasma, you need a metal vapor and sodium can create a vapor at a ... of matter — is matter that is so hot that the electrons are pulled away forming an ionized gas.
