How many electrons are in the “3” energy shell? Electrons are counted, so your answer should be a whole number.<\/p>\n\n\n\n
The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n The “3” energy shell can hold a total of 18 electrons<\/strong>.<\/p>\n\n\n\n The energy shells of an atom are labeled by quantum numbers, and each shell corresponds to a specific principal quantum number (n). The number of electrons that can occupy a shell is determined by the formula:<\/p>\n\n\n\n [ Where “n” is the principal quantum number representing the energy level or shell.<\/p>\n\n\n\n For the “3” energy shell, the principal quantum number is n = 3<\/strong>.<\/p>\n\n\n\n Now, applying the formula:<\/p>\n\n\n\n [ Thus, the third energy shell can hold a maximum of 18 electrons<\/strong>.<\/p>\n\n\n\n Each energy shell is divided into sublevels, which are labeled as s, p, d, and f. These sublevels contain orbitals, and each orbital can hold a maximum of two electrons. The distribution of electrons in the third shell (n = 3) is as follows:<\/p>\n\n\n\n When you add up all the electrons in these sublevels, you get:<\/p>\n\n\n\n [ The “3” energy shell can hold 18 electrons<\/strong> because it contains three sublevels (s, p, d), and each sublevel has a maximum electron capacity of 2, 6, and 10 electrons, respectively. This results in a total of 18 electrons.<\/p>\n","protected":false},"excerpt":{"rendered":" How many electrons are in the “3” energy shell?
