Instead of having three electrons in the outer shell, scandium adds its electron to the second to last shell. Introduction to electron configurations. A stable electron configuration refers to an atom in which the outer electron shell is full. electrons. In your case, the element is said to contain #2# electrons on its first shell, #8# electrons on its second, and #8# electrons on its third. It is only the electrons in the outer-most shell, called the VALENCE shell, that tend to react (be gained, lost, or shared). 1. The electron configuration is 2-8-9-2. Electrons. I mean, one electron from the second shell decays to occupy the vacant space in the first shell, and so one? After filling the first orbit, the second orbit will consist of 8 electrons. Therefore, the electron configuration of oxygen is 1s 2 2s 2 2p 4, as shown in the illustration provided below. This means that the second shell can hold a maximum of eight electrons (2+6=8).

Every element adds one more electron to the outermost shell. Find low everyday prices and buy online for delivery or in-store pick-up are arranged in different shells around the nucleus. Pages 24 This preview shows page 5 - 13 out of 24 pages. Although the third electron shell can hold 18 electrons, the fourth electron shell can hold 32 electrons, the fifth electron shell can hold 50 electrons, and the sixth electron shell can hold 72 electrons, once each of these electron shells gets filled with 8 electrons, the next two electrons will go into the next higher electron shell. I won't vote down because Aufbau is consistent with 4s2 3d6, but the 4s electrons present in Iron are actually higher energy than the 3d electrons and will ionize first and enter last. : electron shells = 2 atomic Orbitals and Subshells: the remaining electron appear!
